I went through a few names to call myself on the Internet until I and my brother decided on the names we use now. He suggested the name Reading for me; it resembles my real name and fits my personality. I liked the name because it was unique, and I don't like unecessary numbers or symbols in my name, so I stuck with it.
When we were having a conversation about what our strengths in creating are, we said that I came up with original stuff, my friend came up with good stuff, and my brother came up with general stuff. I then suggested "General Stuff" as a name for him.
We quickly established ourselves as Reading and General Stuff, so when I became more integrated into forums and such, and when I created our website, we had our names ready. General Stuff's character is, in fact, a general. You know, army-wise...
