But those are all "organic" phenomena. The grandparent comment that called it "inorganic" seems to be mistaken.
Not the case here though, I see it myself how basically all my old Twitter communities have migrated and things are really vibrant. Block lists, mute words and starter packs mean I we exactly what I want to see, which adds to the appeal.
I only tangentially heard of BlueSky and now suddenly it's everywhere.
I mean ... SiriusXM (hardly a forerunner of fashion) just had one of the DJs mention BlueSky.
Something is definitely up.
Let’s put it this way: if a huge amount of people suddenly find themselves done with twitter, what serious alternatives are there beside Bluesky?
