foursquare

so, what's the deal?  who's on foursquare?  do you like it?  do you hate it?  what's it for?  how do you use it?  WILL you use it? 

it's interesting how there are so many products available that track where you are and transmit that information to other people.  i've just recently started playing around with foursquare after i had vowed not to add any more social networking sites to my life.  something about it was interesting to me.  oddly enough, i don't use the similar "check in" feature on facbook.  but i'd love to get your feedback about it if you have any to offer. 

to foursquare or not to foursquare...that is the question.
