If ZP wasn't on the Escapist, I never would've started coming here, that's for sure, but there's enough good stuff on here to definitely hold me if ZP goes. Hell, I've noticed myself looking forward to Jimquisition more than ZP by this point. That and all the things the LRR crew does, as well as Big Picture (Not that big a fan of Escape to the Movies, but that's because I'm not much of a film person) are way more quality content than needed to hook me to this.
And, as much as this sounds like a cheesy attempt to be nice to people, these forums are probably the most reasonable and least irrationally-hate-spewing gaming forums on the internet, so that's a definite reason to come here (Even if I'm more of a lurker myself, just look at my post count vs my join date).
