Flutter shows you how you're connected to the people nearby.
Well, to satisfy your basic curiosity.
Also it's a useful networking tool. Say you're in a strange town, or at a conference where you don't know anybody. Flutter might reveal that you have common friends with two or three people nearby. Hey - you're not as lonely as you thought you were.
Whenever someone tweets or visits Flutter using a geo-aware mobile phone, their location is recorded.
When you visit Flutter with your geo-aware phone, we can see where you are. (Not precisely enough to target you with our space-based death lasers, but pretty close.)
When you log in with your Facebook, Twitter, or LinkedIn credentials we browse through your list of friends. Then we browse through your friends' lists of friends. That's a lot of people. Then we display all the people who've recently tweeted or visited Flutter within a certain radius of your current location.
You know the line in that Miley Cyrus song where "the butterflies fly away"? Yes, you do. We were humming that while we tried to come up with a brand name. That's the story and we're not ashamed of it at all.
Flutter is powered by MashedIn, which is a platform for revealing connections across social networks.
