One thing I like about Bluesky (and Mastodon based apps, in general) is the fact I can use my domain name. Like, yeah, @bobbyvoicu.com.
Well, Bluesky makes it quite easy to do (go into Profile -> Handle and choose there your domain name, add a DNS field and that’s it).
So now, I have @bobbyvoicu.com at BlueSky.
More complete steps (the one I used) here.
