I'd love to see this with wordpress filtered out. I think most small businesses and personal sites run PHP simply because that's what wordpress uses. Subtract wordpress from the php statistics and you get a real picture of "who's using what" without the skewed "I'm using php because I installed wordpress and I know nothing about building websites". This isn't to say people who know how to build sites don't use wordpress either, I'm simply stating that it would be more accurate to measure sites that aren't wordpress to see what languages are being used by companies on the interwebs.
