I got topic banned a couple of years ago for editing alternative health articles, as I was looking to improve articles that were so very obviously biased. I think the last last straw was demonstrably showing that many of the views of David Gorksi of "Science Based Medicine" regarding acupuncture were in fact, without a doubt historically false!

"Skeptics" should be more skeptical of their own sources!
Since then, I've chilled out quite a bit editing on wikipedia, but obviously wikipedia is far from neutral on many topics and I sometimes put my hat into the ring into some topics I find interesting, and improve what I can when I see changes could be made.
