Some people know a lot about a little. I seem to know a little about a lot, or so I've been told. Occasionally.
My main aim on Wikipedia is occasionally helping out with articles focusing on ancient history, classical music, music theory and linguistics. Somewhat like America's role in the Second World War, I hope to swoop down just as a good article is being polished, contribute small amounts during the finishing stages, and then claim most of the credit.
Just kidding. Wikipedia has been for the past couple of years a useful secondary resource to me for non-academic purposes. I'm merely trying to give a little back where I feel I can - a rare occasion, but one worth celebrating.
