One example: when Heroku/Mongo/Apigee/etc rescinded their support from the Sqoot API Jam after women were offered as one of the perks alongside beer. There are many things to do, but a solid first step is not tacitly condoning hateful speech or deeds. The next step is to create a welcoming environment. It's not obvious how to do it (for example, avoid employees taking a dark unsupervised walk to their mode of transit to go home), but would you want to be somewhere where random anonymous strangers could verbally assault you, and you had no legal recourse? That's the social environment that YouTube has made.
