May be more necessary than usual – I got the feeling that women were overrepresented in the "Founder-does-something-terrible" articles, at least on HN.
Some was certainly deserved, although I'm not sure about the proportionality of the 20th "No, seriously, Elizabeth Holmes is a terrible terrible person!" - article.
Some was offensive, misogynistic, backwards bullshit that I can only hope is highly correlated with the writer's chances at next year's Darwin awards – like about 90% of anything ever written about Ellen Pao.
Some was in between – Marissa Meyer comes to mind.
I have no idea why about a third of men feel threatened by the whole idea, but I believe those are problems that need to be addressed offline. I've seen a few cases where some measures to reduce discrimination succeeded even with some initial scepticism. 1:1 talks seem to work quite well, as does starting with something blatantly obvious (dropping the photo requirement for applicants and blinding the names are two common options in my country). Once you get a team above a certain threshold (around 35% women I'd say) the whole dynamic shifts. Suddenly there's picnics and Tuesday morning runs and journal clubs etc. That's something that everyone notices and I believe it has dramatic impact.
The effects continue with any other measure of diversity you can introduce: having a few different nationalities around is an improvement, having someone with a completely different background can be a plus (met a 75-year old office manager once who was beloved at her startup) etc.
