Ezra is a weird name. Reversing the letters does not really make it more or less weird.
Ezra vs Arze
His use of this name suggests to me he did the same thing as me, possibly also in his teens, of using arzE. I played around with it starting around eleven through high school. Also, playing D&D, I played around with names, including even a code to convert normal names into fantasy ones.
Wonder if people with other names reverse it?
Koenig also joined Twitter well after I did. I went with my usuals (first sneezypb and later ezrasf). Pretty sure if I’d not moved on, I might have registered that username before him.
P.S. I briefly made the title @arze which when the WordPress Jetpack posts it to Twitter probably would trigger the mention feature to alert him to this post. So, yeah, I am a chicken for not bringing it to his attention to get a response.
