Is it known who's behind POB?

Wishing POB all the best, though I think it will be difficult to gain traction outside of Hive. Looking at the rich-list => it's centralized quite a bit (that's not going away + why does the [anon] founder/s have so much?) and the trending page => 90% seems to be about POB itself.

For LEO, I think it will be interesting to see whether they've taken on more than they can chew with social-media, defi & co. Regardless, they're surely the most innovative tribe on Hive and show the most promise to actually attract people outside of Hive (AFAIK they've already done that). What they did should be the baseline for new/existing tribes.
