While no single checkin application has seen truly mass adoption, the combined user base of these apps means at any given time, someone somewhere in the world is probably checked in at a venue you want to know more about. At least, that’s the premise behind Localmind.
Localmind, a startup with apps for web, iPhone and Android, is essentially a question-and-answer layer that sits on top of Foursquare, Facebook Places and Gowalla. Sign up with Localmind, connect to one or more services, and the next time you check in, you could be fed a question about that venue from another curious user.
