Thanks for assembling this @penguinpablo, always interesting to see!
It's a bit sad, though... but shows a fairly typical "use pattern" of groups that break away from other groups: A lot of initial enthusiasm gives way to... slow decline? Indifference?
A successful "move" is just that. And no more. You don't get to just move and then expect some magical "it" to happen... building a community is relentless daily work, and once you've moved you might think "we've done all the heavy lifting," but in fact we've only just started doing the heavy lifting.
Of course, Steem is being helped by the substantial inflow of primarily Asian users, drawn in (no doubt) by the "big numbers" of that site's "trending" page... and I doubt they will become long-term active, once those newcomers determine that they will only be getting $0.01 per post, not $125.00. And that's their particular cross to bear, "over there."
But we still have a lot of work to do here... and it's a long term thing...
Steem and hive missed the first move advantage.
We're done.
We were kneecapped by traitors.
