(Otoh, concerning WP, you can, unfortunately, fit almost anything into the WP mold, or "around" it - at least when you are past the point of having read and understood most of its source code and you know the db layout by heart... yeah, it's terrible and the whole thing works against you if you want to write good, clean, testable code, but it still ends up the cheapest option you can give to a client if you want to be honest with him)
