  We have been on a hiring binge lately and it is very difficult to find candidates who know anything but Microsoft tools. 

Geography.

A buddy in Louisiana who was looking for a job tells me there's nothing but Microsoft stack.

I get the same impression about Florida (I've friends there). Lots of Microsoft. Even the Java apps run on Windows servers. I'd love to see more Python there.
