I used to have a weird .red domain and I always found it awkward to tell people. So I ended up going with firstname@lastname.me and literally no one has got it wrong or looked at me funny.
I had a .co domain, and it was a pain to spell it out to people. "It's like .com, but without m" and people usually got confused, or thought it was a typo and "fixed" it as .com.
I have a .dev domain now and everything seems to be running smoothly, plus it's +20% cheaper.
