Before you book a .social domain, maybe do some due diligence on who owns and manages that top level domain.
And decide that a social.<yourdomain>.<tld> is cheaper and better for a lot of reasons. Just because there is a <knownname>.social doesn't mean I trust it to be owned by the right people and not some dmainsquatters.
Stick to what you have and many people already know and trust :)
@jwildeboer With webfinger, you don't even need to do the <social.>yourdomain.tld part.
Just use "handle@domain.tld", like your email address.
@larsmb
Yes, but this only works for your Handle; a lot stuff talks to the @server.part directly, but as /API/v1 or whatever isn't served there, I have to use [@]wusel@fed.uu.org instead, i. e. the instance's FQDN.
@jwildeboer
@wusel @jwildeboer Sure, but the handle is the exposed part. The rest is an internal detail with less relevance, no?
