Trying to describe my personality on the internet is possibly the most unpleasant task I can imagine.
Forced to do so, I suppose I'll say the following: Serious yet whimsical. Slightly neurotic at times. Loves cause and effect. Generally frustrated when presented with effect and no cause. Creative. Earnest.
I think some of my "explanations" accompanying the various questions on this website probably convey a bit more about who I am and how I think. So I guess you can read those if you like.
