I've been trying to figure out how to determine the use of the .Net stack compared to Open Source OS's.
I have read that Netcraft.com is one place to find out. But when I put in one of my own sites (which is .Net), it comes up as unknown, and when I put in StackOverflow.com, it comes up as a Linux OS and "unknown" server. I thought SO was .Net MVC (has that changed)? Given that Netcraft came up with wrong/incomplete answers in these instances, do you think their statistics overall are still reliable?
