Given the incredibly polished launch of the beta Steemit product I think we can comfortably assume the dev team has a roadmap for dominating the social media space with the Steemit platform. It's really a short leap to implement Facebook's profile/reputation features into Steem. Same thing for Reddit's content organization, YouTube's media warehousing etc. And they are now one of the best funded development teams in the crypto space... I can't see them stopping here.
