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 Ito —The gender profile of Wikipedia (Joi Ito)

Thoughtful speculation. Via Clancy on KairosNews, who traces the meme back further.
