Mastodon users are primarily identified by a user@example.org handle, and you might want
this identifier to be the same as your email or jabber account, for instance.
However, in this case, you are almost certainly serving some web content on https://example.org already,
and you might want to use another domain (say social.example.org) for Mastodon itself.
Luckily, there is support in Mastodon for that, but it might be tricky to set up, and any error
might prevent you from federating with other instances.
