Those are rounding errors compared to WordPress[0]. BTW, I'm neutral on WP. I've used it before and it was fine, but I don't work for Automattic or anything. I think it's the elephant in the PHP room, though. No one can claim that PHP is only used for WordPress, but I bet that the majority of PHP installations are there because that's what WP happens to be written in.
