_Believe it or not - I disagree with this. Sort of. Microsoft is almost completely invisible in the Valley. I worked there for ... well pretty much my entire career. That's what I do - startups - and only one of them went with Microsoft tools. And that was back in 1997 when Active Server Pages was all the rage._

This page (http://www.bizspark.com/one/Pages/default.aspx) tells me otherwise, some hot startups are using MS bizspark. So it's not really invisible in the valley.
