One of the neat things about Bluesky is that you have the ability to use an Internet domain as your handle on Bluesky. So for instance, instead of having @bryanruby.bsky.social as my handle, I now have @bryanruby.com as my handle. In the world of decentralization, this allows you to have the same username no matter what application/platform/server you're on. This is one of the advantages of the AT Protocol which Bluesky is built on.
I plan on writing more about why this feature matters and how it is done at a later date.
