Very excited for 2018, but I feel like there is still a lot of work to do around improving steemit itself, managing incentives around vote buying better, better systems for separating spammy posts from bots selling votes, identifying scams, etc.
I think that steem is going to move lock and step with the success of steemit, and the user retention stats for steemit itself aren't as good as I think they need (yet) to be for things to really take off.
