The gender profile of Wikipedia

One thing that has struck me is that many, if not most, of the people I’ve met from the community who are involved in managing Wikipedia seem to be women. I haven’t conducted any scientific analysis or anything, but Wikipedia seems much more gender balanced than the blogging community. I know many people point out that ratio of men at conferences on blogging and ratio of men who have loud blog voices seems to be quite high. I wonder what causes this difference in gender distribution? —Joi ItoThe gender profile of Wikipedia (Joi Ito)
