We'll see! I've been away from the crypto world for a year or two, and based on my 2-day experience with Steem so far I'm absolutely blown away at how good the user experience has come.
AFAIK, Steem is doing something completely new in the crypto-finance world: it's giving people a non-technical onramp. Until now, to participate in the world of crypto, you've got to be savvy enough to either run rather sophisticated software (miners, BTS witnesses, etc), or you've got to literally buy in. Steem doesn't require anything like that - and that, as you know, is incredibly exciting. Good stuff is coming!
I would argue that the user experience is not that great...yet. They have very little "default" social media features that are available as standard issue these days. It will only get better. Nothing wrong with being blow away but relative to their own potential it kind of sucks. Love the style so far though. Facebook is with more room to breathe.
