I think one readily untapped resource is the ability for steemit to be used by coins for announcements and community updates. It would be nice to see some of that move from bitcointalk.org over to steemit.
Don't know if any of that data could be used to convince coin creators to move their announcements and/or communities over here.
Even better, using predictive analytics we can even know which accounts are more likely to participate in ICO, and what sort of ICOs interest certain account holders, which sort of projects would interest certain account holders, who to hire for certain projects based on knowledge, all sorts of stuff. So yes, you have a gold mine of data on Steem about the community.
