But the point is that just because it was a bad idea, doesn't mean Koz is categorically a bad developer, or that he's any of the things that Zed called him. I heard him talk at RailsConf, and I have to admit that he sounded kind of like an egotist, but didn't actually know how to code all that well. But do I call him a fat fucker? No. That's taking it a little too far.
