http://www.foursquare.com/ IB4 it gets big fellas I just added the app on my N900 They have apps for Blackberry, iphone, Android You basically use the app to "check in" to places you hang out IRL. Why? Achievements. kinda like Xbox live. Here is more info http://foursquare.com/help/
Meh, I used it a little over a year ago.....unless you have a lot of friends using it, it was not much fun. DD
I used to use brightkite and loopt... etc... one of them was bound to catch on eventually. Not really sure I would do it again unless I was in a big city and had a lot of friends using it.
before it gets big? It's been pretty big for a while now.. people that link it to facebook are getting annoying as crap though.. wayy too many posts anytime they are walking to here or there. I'm almost to the point of blocking foursquare from my news feed (and the only other things i've blocked are Vampires and mafia and that kinda stuff) And yeah, it got old after a while. Especially when my friends in my city stopped using it
same thing was said about twitter more than a year ago. I think the apps are going to make it more popular, hence: more people/friends. more for nightlife types (no offense) anyways.
