No, STMs are not yet live, but a subtle change in the way Steem is publicly presented hints at an imminent launch.
While doing my mandatory weekend browsing in the repositories under the steem umbrella, the description below just stood out.
I don't know when this was changed, I just saw it now.
Given the fact that the SMT technology wasn't yet launched - albeit the development has been very fast paced and thorough, as far as I can tell by watching the Github activity - this is quite a bold statement.
Strategically, it aims to position Steem as a core technology, and not just as a social media blockchain.
And that's a completely different game, putting Steem in the same territory with players like Ethereum or EOS.
Later edit: by looking at the Wayback Machine, I pinpointed the change sometimes between November 7th and November 22nd last year. Before that, the Steemit tagline used to be: "A social media platform where everyone gets paid to post. https://steemit.com"
