Let's say he didn't post or publish anything, would you say he'd be better off? I'm positive he won't.
I'm sure he'll find something worthwhile, tho, because of his presence. So overall, it will help him.
If he wants a management position, not so much, IMO.
What qualities does he bring that would make him a good leader? It's his way or the highway, he's always right, everybody else are idiots, has a taste for drama...
Yep, just what any struggling organization needs. Dissent is fine, what Zed brings - just in a blog - would suck to work with.
I think he's a good programmer and self-promoter, but nothing of his that I've read would lead me to put him in charge of something. In a few years, when he's matured some, maybe.
