If you want to see how much there's interest among developers in Steem compared to Ethereum... Steem doesn't even show up on the map while you can find more than a dozen courses offered by the universities (via coursera) that are teaching the developers about blockchain development on Ethereum.
This is what I mean though. How much is there out there at the moment for anyone who isn't a dev or a trader? I have no idea but it seems that it is pretty much all like this post, very specific and self-referential =)
Once Voice goes public I think it will surpass Steem within weeks, even with the stupid ID requirements.
I think so too as most people dgaf about their prvacy, they will move over from Facebook. I think that some of the SMTs will do similar and have KYC involved, I don't think Steem will though.
