Is there a lot of sexual harassment/chauvinism on wikipedia also?

Personally, I've observed vastly more sexist/chauvinistic behavior on Facebook (where women seem quite happy to contribute) than on OSS mailing lists, but that may just be an artifact of the people I interact with.

Another question: can anyone think of other free/for-pay intellectual activities which do/dont exhibit a gap? We can compare OSS to paid programming, Wikipedia to Demand Media, are there other comparisons of this sort one can make?
