Personally, I have firstname@secondname.email That was a domain I set up when I was self employed, contracting for people, trying to look ‘professional’ I still use it to this day, though the professional requirement is gone now since I’m employed by a company. Still, it’s catchy and not that expensive, so I keep it, and renew for long periods of time.

Then I have another domain, not personally identifiable, for whatever stuff I want to host/play with. This one is a three letter .ac domain for 10 years for $200 ish. The three letters are my initials

So you say, is there usefulness in having a real name domain? Not unless it’s your business. For me, when I was contracting, it was a simple attempt to get clients to remember me over the hundreds of others

To me, ones like joeblacktechnicalservices@gmail.com always seem like a lazy attempt, for a ‘business’
