Disagree with both the analysis and conclusion of #1, but all of the others are good points, albeit at varying degrees of specificity and implementability (the last few are especially vague). I'd be all for #2 and #3 and I think they bear the greatest responsibility for Steem having a terrible reception in the market, which in turn leads to the price declining almost always, though the 80% ninamine and accompanying 800K STEEM/month sell off (essentially more inflation) are part of it too.
Ironically I think #3 alone might be the most serious problem and at least the long-lockup component would be very easy to address without any sort of profound platform or code changes (just change 13 weeks to 1 week). But several people have been and I guess are still thinking that long lockup is a good idea, as hard as that is to believe.
BTW, more support for @burnpost not only reduces immediate inflation but could be seen as a vote of confidence for #2.
