FourSquare

Anyone else use this? http://foursquare.com
I like the idea, it's pretty fun, and if I owned a restaurant, gym, store, I would be all over it.

But man does it make me feel boring!
I go to the gym, CostCo, and to my daughter's activities, and that's just about it...nothing like technology to make you feel old huh? You can check me out here

What do you think of this? Great for letting your best customers let others know great things to do at your business/event (at least that's my opinion of it).

I feel like a couple of my favorite hangouts, Matt's Bar and Chatterbox Pub could really do a lot with this: mayorships, group check-ins, to-do of the day, ect.

What do others think?
