What about Facebook?
Shouldn't it be possible to write an app that integrates Fluther with Facebook? I'm thinking of apps like the "where I've been" that are written by outside parties, but that people can add to their profiles. Couldn't there be an app written where people could ask questions via a Facebook app, and track the ones their following via an RSS link to that app? Then people could add the FlutherFacebook app to their own profiles as they see it on their friends' pages.. the growth would be MIND-boggling!!
