There are people who have a rosier opinion than I do of what Twitter was pre-Musk acquisition. Speaking as a broad and maybe unfair generalisation, I think that crowd – call them the nostalgics – has been drawn towards Bluesky as the most one-to-one replacement for what they once had and now miss.
(In the past handful of days we've gone from almost no Bluesky followers to 4,000: https://bsky.app/profile/canongate.co.uk )
Call me a dead-hearted cynic, but the (hyper-capitalist) pressures on Bluesky seem to me to be the same pressures that did for Twitter in the end – and I'm not desperate to relive that cycle – but maybe if that's where a lot of our community goes then we'll end up being active there and enjoying it while it lasts.
