I like Foursquare explore because everyone in my office uses it. If I want some overpriced, whole-grain, organic and unprocessed artisanal foods that will leave me feeling like I can punch through cinder blocks, I look for places that Steve checks into, cause that guy loves that shit. Also, he sits across from me, so I can say "Hey Steve, you've been to Tony's Sandwiches, what's it like?". Or maybe I want some really cheap greasy bullshit, and I know that Dave is a cheap bastard, so I look for places that he's checked into. Etc. Searchable, local reviews by people I know. It's not useful if you don't have friends that use it. It's kinda like last.fm: not actually worth using until you're already using it. Some things you have to see to believe in; others you have to believe in to see. Foursquare is the latter, not the former.
