[ArbitraryLimits]

I wasn't arguing the "women aren't good at programming" position.

My personal opinion is that the most important reason there are few women programmers, next to which any other factor fades into insignificance, is that women are simply less interested in doing it. Now that I think about it, the fact that there used to be many more women programmers when women's career options were more limited is pretty strong evidence that this is true: Now that women have more options, there are fewer women programmers.
