Coincidence or not, I dunno, but he seemed to stop posting when I edited his last post and sent him a PM telling him to stop with all the 'Heidi Klum' links.
If that's his reason for leaving, fine. These forums are about audio.
As for his growing "weary of childish behavior amongst peers", I'd say if this is the case, he should develop thicker skin, as this forum is tame compared to any other forum (or the real world, for that matter).
I'll say this much, it certainly takes much less time to get caught up on the forums now, but he's obviously welcome to post if he wishes...
