Slight sarcasm - I’m also a Mint user, and it was like a recursive reference to this meme from forever ago. Maybe it was too specific and dated, but the point is that since Macs were so easy to use, the Windows people back in the 8.1 days treated Mac users like kindergartners as they paid for their $1,000 facebook machines (also a meme from that time).
All the “Yeah, I use Arch, BTW” people that love the struggle and the hobbyist tweaks of their distros seem to look down on Mint users because it doesn’t require a struggle to use Mint. I used to see it all the time when I first jumped over to Linux.
It can look professional when you aren’t posting a gmail address and the domain isn’t poopypants.net
Pick something neutral that isn’t your name. Try a band name generator. JupiterEvolition.net or IdealMachine.XYZ,.which sound better than herpderp common gutter trash Gmail.com
Having a custom domain means you get things like [email protected] and also chosen.one@… And bestcandidate@… Etc. So you can make something for professional stuff, and then [email protected] to be funny.
