Is the Wikipedia contribution process so fraught with competitiveness that women are intimidated? Are women less interested in showing off how much they know? Are they too busy in the real world with jobs, families, and social lives? Do they object to writing articles for no pay? I don't know. I'm really baffled.
I admit I don't contribute to Wikipedia either, though I'm an avid user. My excuse? Um, the process actually does intimidate me a bit. Plus I'm not interested in getting into arguments about the typical things that get argued in my field. Who really cares what OSI layer ARP runs at, or whether ping stands for Packet Internet Groper? Also, if I spend a lot of time researching and writing on a topic, I don't want my work to get edited by somebody who likely knows less than me. Sorry if that sounds arrogant. It sounds a little like a man, actually, doesn't it? :-)
