regarding #3 -- I kind of despise the Valley in this regard. When you are a tech firm not in the valley, inevitably you get a middle-manager type that comes in and tries to emulate what the latest hip SV firm is doing to boost your street cred. When I look around the offices I have worked at in the South, and up in D.C. in the 00's and early 2010's, we have never had a diversity "problem". There was plenty of diversity, not just male/female diversity, but also multicultural diversity, and diversity of thought and opinion(I've actually worked with some conservatives! They are real!). SV to me pushes their "we have a white male broculture" projections out, so suddenly now it's everyone's problem. Now we have to be explicit with our "diversity" initiatives, despite the fact that we were already much more "diverse" than the SV intellectual and social monoculture you have now.

Anyways, just kind of ranting, but yeah. SV's problems in tech somehow always branch out to be everyone else's problems that are in tech, at least media and high profile twitter accounts and bloggers would have you think that, but it isn't really so.
