"I see with WP is that it doesn't do mauch to encourage most people "developing" on it to ever consider other tools; they just learn to fit more and more jobs in to the same ecosystem, whether it's a good fit or not."

Spot on. I do a fair amount of WP work. I'm a member of a number of WP groups on FB. I see this all the time. For most people WP is a hammer and everything is a nail.

Unfortunately, that's the Kool Aid served by Matt M all the way down. WP isn't an OSS application. It's a cult.

To the majority of the cult members there's nothing else. They know nothing other than WP. Truth be told, most of them don't even know WP.
