Experts-exchange faces the same problem in StackOverflow that the proprietary UNIX vendors confronted in Red Hat and Cygnus.
The open source vendors were perfectly happy to turn a hundred billion dollar industry into a one billion dollar industry, as long as they sat on top of the smaller stack.
StackOverflow is clearly happy with a large piece of a smaller pie, and the "evil hyphen guys" are never going to be able to compete with that.
