A reminder, if you own your own domain you can quickly setup webfinger like this https://www.hanselman.com/.well-known/webfinger (can just be a static file, or dynamic) so that if someone searches mastodon (use me as an example) for @shanselman then it will call out to my domain, find me, and tell you my aliases, which is my account at hachyderm.io. Cool eh? Should take you just a few min to implement!
@shanselman if they just search for your mastodon username how do they know to check that domain?
If you said if someone searched mastodon for hanselman.com then @shanselman would turn up that would make more sense to me.
