It feels like Bluesky missed their chance to be the twitter alternative after how well Threads has been going. I'm sure zuck will find a way to ruin it but its gonna be a long road a head for Bluesky.
As popular as it is among specific groups, I can't help but feel the decentralized push is going to hurt adoption. Maybe not as badly as it hurt Mastodon because they do supply a "default" server to join, but most people in my experience, don't want a decentralized platform and enjoy the benefits of a centralized platform quite a bit. I suppose time will tell.
I do like how usernames are domain names, which gives them a portability similar to email.
