I'm using and liking a subset of C++ myself...
But for web development, it seems like quibbling to even mention all the reasons it generally isn't used in normal web development - lack of portability, need for compiling and the real and perceived danger of a binary that might run on a server you rent from someone else. Then that said, I have worked on C++ web backend stuff but it was kept well away from the realm that Ruby/Python/jsp/asp inhabit for all these reasons.
