It's a funny thing: people either love it or they hate it. Or, they have no idea what Foursquare is. If the latter describes you, watch the video, above, before reading more.
Anyway, we recently joined Foursquare as "All About Fifth" and we'd love to interact with more users. So, go to Foursquare.com/allaboutfifth and add us as a friend! We try to drop by Fifth Avenue area venues on a regular basis and leave tips and we hope to get some great tips from you, as well!
