Don't confuse money changing hands with "trust". Even with large corporations buying Microsoft stuff, which tend to use "safe" technology (Nobody got fired for buying IBM), it's interesting to note that MS still only gets half that
market and still only 22% share overall. And we all know how aggressive MS can be.
I don't recall if it was NetCraft or not but the numbers are also skewed by just three organizations: Facebook, MySpace and one other (I forgot). Removing those three companies greatly diminishes IIS usage.
Yes, MySpace is a huge contributor to IIS's marketshare. I think it serves all the tens of millions of profile web pages.
Anyway, let this thread die... its only four years old.
