I would venture to say that photo sharing apps are the PREVIOUS geolocation apps.

While they may be new as phone apps (as opposed to web apps), people have been sharing photos in a million different locations and ways for years (Twitter, Flickr, Facebook, Snapfish, OFoto, MobileMe, Picasa, Email...).

As it stands right now, I can't see Path solving any problem for me that isn't more easily solved by any number of already existing and wildly more pervasive tools.
