Now more than ever, fundraising for charities, campaigns and causes is taking place online. A variety of startups offer simple ways to power fundraising campaigns online, including GoFundMe and Facebook app Causes. Nadanu is another contender in this space, with its Push-K giving solution, offering non-profits a way to power fundraising on the web and mobile devices as well as social networking sites.

Nadanu’s Push-K platform allows register and “drop coins” into a custom receptacle. It is modeled after a traditional charity coin box, and donors can click to drop virtual coins into their eCharityBox and watch it fill up. Once the box reaches a predestinated amount the box is emptied, their credit card charged and an automated tax receipt is sent via email. Payment options include Authorize.net and PayPal.

The interface is sleek and easy to users. On the backend, Push-K allows organizations to deliver content such as video and audio and also serve text messages to users.

Launched a few months ago, Nadanu is already powering e-giving for over 400 charities. Nadanu also has mobile offerings available for the iPhone, iPad, Android and more. And the company has a web offering and Facebook app.

As you may have heard, Apple completely blew through its pre-order launch day iPhone 4s in less than a day (and that was despite major technical issues with the ordering process). It has now blown through the second wave (due in early July) as well. The current shipping estimate if you order right now is July 14. Ugh. But if you absolutely want one at or around launch day, the Internet, as always, provides an option.

Scanning eBay right now, there are roughly 400 iPhone 4s for sale (between the 16 GB and 32 GB models). Sure, the device isn’t out yet, but people are willing to part with the device as soon as they get it on June 24. The question is: how much do you have to pay to get them to part with it? Currently, the cheapest ones are going for $550 — and that’s the $199 16 GB model. The cheapest 32 GB model? $799 — a full $500 over the $299 retail price.

Both of those are bargains compared to what some people are selling them for. Want the iPhone 4 hand delivered to you by June 27? That will cost you $5,000. Yes, $5,000 for one iPhone. At least 50 other people are offering to sell their’s for $1,000 or more.

And this is just two days after the initial pre-sale. As the expected ship date continues to get pushed back, these prices are going to get much more ugly. By the time launch day hits and people have them in their hands, don’t be surprised if many of these new iPhones sell for thousands of dollars.

Since April, Twitter users have grown accustomed to Twitter’s first ad revenue play: Promoted Tweets. Today, the second phase of that strategy is starting to be tested: Promoted Trending Topics. The first such topic? Toy Story 3, promoted by Disney/Pixar.

As you can see in the right hand toolbar of Twitter.com, at the bottom of the Trending Topics area there is now an 11th topic, “Toy Story 3.” Next to it is a big yellow box letting you know that it’s a promoted Trending Topic. Just as with Promoted Tweets, the functionality for these Promoted Trending Topics is the same as the regular Trending Topics — clicking on it takes you to a search results page to see what people are saying about Toy Story 3.

“As we have always said, we plan to test different advertising and promotional models in these early stages of our monetization efforts for both user and brand value. As part of this effort, we are testing trends clearly marked as “promoted” for an undefined period of time,” a Twitter representative tells us.

And along with buying the Trending Topic, Disney/Pixar gets a Promoted Tweet at the top of the stream, Twitter confirms. Twitter also says that just as with Promoted Tweets, the Promoted Trending Topic “has to resonate” or it will disappear.

Two more things of note here. First, it’s interesting that Twitter is putting these at the bottom of Trending Topics rather than at the top. Still, the yellow badge draws your eye naturally to it. Second, the Promoted Trending Topic appears no matter which city or country you set your Trending Topics to. In the future, you can imagine these Promoted Tending Topics being even more highly targeted to just certain regions/cities.

Every few weeks, Google’s Android team updates their Platform Versions page that breaks down how many Android devices are running each version of the OS, based on data from the official Android Market.  Today’s it’s reached a big milestone: exactly 50% of Android phones are running 2.1, the latest officially released version of Android (2.2, or Froyo, went live for a small number of users last month, but has not officially been deployed on a wide scale).

This is a big change since early May, when only 32.4% of phones were running 2.1. Since then, a number of older phones have been upgraded, and the new Sprint Evo and some other newer devices run it as well.

So why does this matter? We’ve written pretty extensively about Android fragmentation, or the fact that there are many phones running older versions of the OS. The Android team contests the use of the word ‘fragmentation’, (one blog post actually calls the term useless because it has been used in so many ways).

But the fact remains that nearly 50% of phones are running older versions of the OS, and if a developer wants to make use of the latest Android features, they’ll leave a big chunk of the Android userbase behind.  Case in point: when the official Twitter application was released in April, it was only available to 27.3% of all Android users.

Still, the tide appears to be turning. OEMs are going to get faster with their updates, and Android upgrades will eventually start coming more slowly, which will hopefully result in fewer phones getting left behind.

The Playstation Move is just what it looks like: a Wii clone. It feels the same, looks the same, and works the same. That’s a good thing, though. Everyone and their grandmother has played Wii bowling and knows how it works. Sony isn’t reinventing motion control with the Move. They are, however, seriously improving it.

When Hot Potato launched at our Realtime Crunchup last November it was already a solid app. Then came a new version in March (just before SXSW), and it was even better. Today brings version 2.0 — and it’s the best yet. And it’s also different.

When it first launched, Hot Potato was basically an iPhone app that let you build a social stream around events happening at any given moment. Right before SXSW, the newer version of the app added killer Foursquare integration, and tied everything together with the service’s website. The update today shifts the focus away from events, and makes it about all kinds of activities. Really, anything in the world you may be doing, you can now “check-in” while you’re doing it on Hot Potato. It’s actually pretty cool.

When you load up the app, you’re taken to a screen with six default prompts for what you may be doing. Those six are: “I’m watching..”, “I’m listening to..”, “I’m attending..”, “I’m reading..”, “I’m thinking about..”, and “I’m playing..” After each, there’s a box to fill in the noun that should follow each of those. When you enter that, Hot Potato searches to see if it’s already in the system. So, for example, if you say, “I’m watching Lost”, Hot Potato finds the other people doing that as well and ties you altogether into one activity.

Within this activity page, people can comment and respond to comments about the activity, just as you previously could in Hot Potato. You can also add pictures to this stream.

There’s also a seventh activity option in which you choose your own verb. Hot Potato gives you a list of new options (such as “I’m eating”, “I’m drinking”, “I’m checking out”) — or you can add your own. This reminds me a bit of the service Plurk, which is a Twitter-like service that allows you to organize your status updates around verbs. But obviously, this is more robust.

Just as before, when you fill out what activity you’re doing, you can send it to Twitter, Facebook, or use it to check-in on Foursquare. The way Hot Potato has set this all up is quite seamless. And there is of course an activity stream front and center in the app to showcase all of your friends’ activities.

There’s also a new element: awards. Yes, just as with some of the other location-based services, you can now get badges for doing certain activities. For example, when you share your first activity, you earn the “You’re a Big Deal” award.

Hot Potato 2.0 also brings a revamped version of the website to match this new activity focus. And for the first time there’s an iPad app as well.

We’re already seeing a ton of Foursquare-like services that let you “check-in” when doing various things. For example, Miso lets you check-in around movie, television, and Internet video content. This new version of Hot Potato aims to let you check-in no matter what you’re doing. And it smartly ties in with Foursquare.

This morning, a number of major advocacy groups, including the ACLU, EFF, and CDT, sent Facebook an open letter detailing some of the outstanding issues with Facebook privacy. The groups’ letter acknowledged that Facebook has made strides recently on this front, especially with its launch of new, simpler privacy controls, but that it hasn’t addressed some major privacy issues, like the fact that the controversial Instant Personalization feature is automatically opt-in.Wasting no time, Facebook has just responded with an open letter of its own.

Along with Instant Personalization, other issues addressed in the advocacy letter include the fact that Facebook is able to track user browsing behavior through its ‘Like’ buttons and other widgets (these widgets are served up by Facebook to third-party sites, so it can see which sites you’re visiting). And the letter says that users should have more control over what information third-party applications should have access to. Finally, the letter asks Facebook to give  more control over what information mandatorily made public, and the ability to export data so that users can easily transition to social networks other than Facebook.

Facebook’s response addresses each issue point by point:

• Regarding the so-called “app gap”, Facebook says that it is implementing a new data permission model that will be rolling out in the next few weeks. There’s also now an option to turn off Platform entirely.
• Facebook’s response to the Instant Personalization is pretty weak — it says that the program has been “widely misunderstood” and that partners can only access users’ public information. I understand the program quite well, as do numerous other critics, and, I’m sure, the likes of the CDT and EFF. And it’s obvious that there are still issues with handing over “public” data, especially when some of that data was switched from private to public during Facebook’s privacy transition in December.
• Regarding Facebook’s ability to track users through its widgets, Facebook says that it does not use that information for targeting and that it is deleted after 90 days.
• Addressing the point about giving users more control over what information they can hide, Facebook effectively says that it’s given users more control than they had, but that it finds that users have a “more meaningful experience” when they share more information. In other words, they’re still going to force some of this information to stay public.
• Facebook says that it is currently testing SSL access to Facebook (a good move).
• Regarding the ability to export data, Facebook says that users can already do this via its APIs. It then takes some shots at the advocacy organizations saying that it is “surprised that these groups would advocate for a tool that would enable one person to strip all privacy protections for any information that has been shared with them”. I’m pretty sure nobody is asking for that.

Here’s the full letter from the advocacy groups:

And Facebook’s response:

At the risk of pissing off our new office neighbors, I have a confession to make: I loathed the Yammer iPhone app. Don’t get me wrong, I love Yammer, and find it absolutely vital to our work. But the app was easily the least stable of the dozens of apps I have  on my iPhone. It was so bad, in fact, that I’ve been accessing Yammer through mobile Safari in recent weeks. But that’s why I’m happy to announce that today, with the launch of the latest version of the app, 3.0, my nightmare is over.

As they note in the App Store description, Yammer 3.0 for iPhone is a complete re-write of the app. It promises to fix “many crashes,” load “much faster,” and even work on the upcoming iPhone 4. A quick run through confirms all of those things. The app’s UI has also been overhauled and is much more pleasing to look at now (and is actually simplified). This looks to be an all-around win.

It also brings several smaller features such as: autocomplete for @replies in the app, full landscape support, and the ability to mail and call contacts right from within the app. This thing just made my job much easier. Nice job Yammer, you’ve earned your way back on to my main screen of apps.

You can find the new Yammer app here. It’s a free download.

Update: Fine, I’ll change the title to “fewer”.
