I think "solution in search of a problem" is a fine description, and not really a bad thing. Nobody says "I want a photo sharing app" and downloads Snapchat after doing some research. You get it because your friends have it, and you keep using it because you enjoy it. If your friends aren't using it, then you won't like it because there won't be anything to do.
