Since the namespace for Instagram is pretty controlled by them, it'd be nice to take @username mentions in posts and convert them to http://instagram.com/username/ links so they keep working
I suppose the other option would be to go look up what the "real name" behind that username is and change to that? (I guess people can put whatever they want there)
