This allows people to search for you under your own
@user@domain alias, finding your account on whichever server it currently resides on. This has a lot of advantages when it comes to discoverability!
If you move servers, you can update the
mastodonHandle value to reflect that; searching for the alias will then direct people to your account on the new server.
@email@example.com on your Mastodon server and you should find my account—if the search isn't currently broken because it's too busy.
