Well, the post does imply that they've had problems recruiting exactly because they're using PHP. It's no mystery to me either, I imagine it must be hard to find great engineers willing to spend all their days dealing with the idiosyncrasies of PHP. Great salaries is a great thing, but what if your competition offers great salaries and a less obnoxious programming environment than PHP (and better hardware, and better office space, for that matter)?
