I changed it. It used to be Teratagon, but people kept asking me how it was supposed to be pronounced. Then Deej misspelt my name as "Tetragon" in a Weekly Update. After being mildly-not-actually upset at him for that for a short while, I adopted the name Autocorrect chose for me. I became Tetragon, Lord of Four-Sided Shapes, mostly because it's easier to say.
