I wish I could find my old account from when I used to edit more frequently, I'd love to see my old changes and what happened to them. But I don't remember it at all any more.
I'm going to use this one almost solely to make pedantic edits to articles. You know, things like unit conversions.
Maybe when I stumble across an especially bad one I'll revise it more significantly-- But it's been a while, wikipedia's editing just continues to get better as time goes on.
