I worked at one of the most progressive / women-friendly companies in San Francisco, and as of last year, only 34.3% of our technical roles were filled by women (company size ~1,000). I'm eager to see this year's numbers, and hope they've improved, but there's undoubtedly a lot of room to grow.
You may feel uncomfortable knowing the hiring process is weighted. But I feel uncomfortable being in an office that doesn't have other women. If I can change that WHILE at the same time meeting my hiring standards AND not consciously turning away a clearly better candidate then absolutely, I'm going to use positive discrimination.

In spite of this, I'm lucky to have an amazing network of other women in my field, and thanks to the internet and cultural exchanges, we don't feel so alone these days.
