carrideBluesky now platform of choice for science community

FWIW, Bluesky still seems unfriendly to email alias providers.
I never managed to create an account on Bluesky as one of their support email blocks certain email domains. They still have a long way to go.
It's so odd that they still get to enjoy their status as a "decentralized" "open" social network when it's really just a centralized platform by definition (and it's not even their fault, there is simply no way to do what they want to do without centralization).
Sure, someone may say "the AT Protocol is open", but that means nothing because the AT Protocol is not Bluesky, Bluesky is one centralized platform that happens to "talk" that protocol (well, of course, since the "protocol" is literally defined by whatever they happen to be doing), it still controls who can be inside and who can't.
TL;DR: Nostr is a much better option for most use cases, sadly for some unfortunate reason it never got to enjoy too much attention from a wider technologist community.
You're free to set up your own PDS (which is super easy) and use Bluesky through it, and it works just fine (or even better if the PDS is close to you)
