Yes, SMTs were planned to be launched in March. But that was ages ago. Enter capitulation in November and Steemit Inc put everything except MIRA on the back burner. The old release date was still floating around in the cryptosphere to which investors reacted as the lemmings they are. 

If we want a higher STEEM price, some sort of marketing is an absolute must. The information out there on Steem is simply garbage. It doesn't help that a number of frustrated Steemians have quit because of past mismanagement by Steemit Inc or because many of them saw their rewards tank after the unsustainable initial pump - and continue to badmouth the project.

Steemit Inc may publish new release dates in the near future because, as far as I know, they are planning to get SMTs done after MIRA has been rolled out and the kinks ironed. But we don't really even need SMTs because we have Steem-Engine. The cryptosphere knows practically nothing about Steem-Engine. With all the recent developments, I think STEEM would deserve to be priced at something like $1-$2 rather than 35-40 cents.
