Steemit INC is still foolishly racing toward SMTs. They aren't going to look back until they finally release HF21. At the same time, SMTs are pretty damn important, so it's hard to say that what they are doing is wrong. My guess is that Steem won't be a great blockchain until a year after SMTs come out and we've finally had a chance to calm down, document the API and work out all the bugs.
