My activity in this sort of enterprise began on Everything and Everything2 (http://www.everything2.com) in 1999 but, when there, I was more interested in factual articles than creative writing and opinion, and found flaw in the inability to correct the errors of other writeups. I have been a registered user of Wikipedia since January, 2004, and may have been active before that. I do recall, I think, proof-reading a few articles on Nupedia.
I am interested in universal knowledge, which may be described in general as physics, ethics, and logic, as well as its particular applications to technology, history, language, and literature, which inform the human condition. I have a keen eye for logical fallacy, rhetorical nonsense, and dictional and grammatic infirmity.
