Yes this. It clearly seems to have emerged as a result of Twitter’s direction since, near as I can tell, Dorsey only started down that path when it became clear that Elon might not be the savior he’d hoped for.
In which case I’d hope bluesky planned for the possibility of a rapid decline driving people to <alternative> and made plans for very rapid scaling and it’s just that implementing them is still non trivial.
And/or they didn’t imagine the occurrence (somewhat reasonably) of multiple events on the magnitude of those from the past week driving so much interest this fast. I don’t even use Twitter but the recent news, and awareness of a (hopefully) healthy alternative that I might find worth my time, how driven me and probably other like me to turn to interest. How does one even get into it?
