True, it could have been an honest mistake. However, like I said in my comment above DHH starts off the post wondering aloud about Zed's state of mind and whether he needs help. Even if the Mongrel thing was a legitimate error the opening paragraph is an obvious cheap shot. Regardless of whether or not Zed just has an axe to grind here that kind of nonsense makes DHH look like a tool and a half if you ask me.
