> P.S. Sadly, I think enough people have left Twitter that it's never going to be what it was again.

Majority of those people came back after a while. The alternatives get near-zero engagement, so it's just shouting into the wind. For the ones that left over political reasons, receiving near-zero engagement takes all the fun out of posting... so they're back.

I'd be willing to bet that 95% of my "followers" on Twitter are bots. So I get near-zero engagement, or engagement that is worth zero.
