Pingdom blog has posted a list of woman open source project contributors around the world. From the blog post:
We here at Pingdom have been talking about why we don't see that many women in Open Source, and were actually about to investigate it further and possibly write a blog post about it. However, when we started to actually look around we were happily surprised. There are lots of women involved in Open Source! For some reason men just seem to stick their nose out more and put themselves in positions where they are seen (and of course there are more of them).
