I jumped on Bluesky, Mastodon and Threads during earlier exodi. They all waned for various reasons (Mastodon was slow and unreliable, Threads was basically an Instagram feed of nothingness, and Bluesky was dead at the time).
This wave does feel very different though. People joining in large numbers (I gained more followers in a day than in a year on Mastodon). The Bluesky app itself is actually very nice. Twitter is becoming more and more unbearable with the force-feeding of ads and totally broken search (that's without even mentioning the post-election environment).
You might be right, but I do feel like this time is different. Let's check back in 12 months and see.
@nickfisherau.bsky.social if anyone wants to say hello.
