Friends Around Me is a mobile app for iPhone and iPad that searches around you for nearby friends — or anyone else willing to say hello — and enables you to view their profile, look at and rate their photos, chat with them, or send them virtual gifts.
The service joins together your Foursquare, Twitter, and Facebook networks, allowing you to check in to venues and update your Twitter/Facebook status from one place. Best of all, the service doesn’t require yet another social network registration: you can sign in using Facebook Connect or the Twitter API.
One cool thing about the service (that will probably freak out the privacy paranoid) is that there are no restrictions on whose profile you can view, or who you can chat to. Plus, you get to see and respond to everyone who has viewed your profile, making it a great tool to meet new people. Of course, there are options to hide yourself from strangers, but where’s the fun in that?
