This really isn't what Foursquare is anymore. It's become a rather good location database & discovery platform.

I never used it when it was "hot" (~2012), but in the past few months I've really come to like it for finding places (restaurants, etc.) & making lists. Also, their tools for making edits to the DB are quite impressive, and they do a great job of leveraging superusers to moderate those changes.
