Like you I dislike the way Zed has a tendency to group all Ruby people together and target them as a whole, when in reality his complaints would be better directed at a specific subset. I'm a Ruby dev (not a Rails one) and it stings when Zed fires his literary shotgun at Rails, and Ruby, standing next to Rails also gets hit.
But... this isn't about Zed being a dick. I was pointing out that there's also a massive amount of good stuff he's done as well. I'm not a fanboy of his (Zed has fanboys?) but I do have a fair bit of respect for his ability and what he has done, and his writing does nothing to diminish the quality of his work.
The comparison with DHH I thought was positive. DHH has strong opinions and (it appears) an ego to match, but can back it up with code.
His online persona has one truth - he spits into communities.
And to compare DHH with Zed is unfair to DHH. DHH never made such idiotic rants like Zed.
