I wonder if you have trouble giving your email over the phone.
I have a <name>@<name>.net email. And every time I'm spelling my email to someone, I say: name, n a m e @name.net, 99 times out of 100 they ask me if the second "name" is spelled like the first one.
I have a friend whose surname was McCurry (which she rarely used - family baggage) and she ended up changing it to Blake, because you never have to spell out Blake to people, but you do every time with McCurry.
Yeah .... I had the same problem with a common first name + last name @gmail - even to the extent of getting someone else's buddy passes for JetBlue - before getting my own domain. I thought it wasn't bad for my purposes, but it's a terrible domain name for spelling out (my handle here plus .com).
1. Use a handle that is a deliberate misspelling of an archaic name, and;
2. Use an archaic spelling of my surname as a vanity domain.
