Facebook is really pick about their buttons and keeping anything that goes into the News Feed tightly controlled (I don't think it's a bad call by them, in my experience, the News Feed ads have been pretty relevant to me, and I don't feel overly spammed). "Use App" could definitely use some work, but I'm not sure if I have a better general purpose call to action to suggest, and it seems like most of the use cases are covered by the other options (at least for now). Maybe in the future they will allow some kind of user submission that they can approve to allow a bit more flexibility? Twitter cards are incredible, and really promising. Now Twitter just has to figure out a way to get people that advertisers reach with them to actually spend money (not to mention the miles they have to catch up with Facebook on attribution and conversion tracking).
