At least that's my take on it. Slinging numbers like 100 and 0 is generally a sign of hyperbole.
My problem is that I'm tired of all these articles proclaiming "Skub considered harmful"[1], "Why Skub sucks", "Skub on rails sucks!" or "Skub ruining CS degrees".
But it just goes round and round and round.
Someone says something bad about Skub then another 6 blog posts pop up defending it and how the author is a douche. Then it just burns through the blog-sphere like a wildfire before burning out. Ready to start again!
Java makes programming difficult. Some people like that. Many don't.
Ruby makes programming easier. RoR makes doing webapps easier. This guy's premise, that there is no overarching philosophy to RoR, is incorrect, and shows unnecessary ignorance and anger. You have to wonder if he's just projecting.
I'm frightened by such an uniform behavior in the YC community. By dismissing any dissenting point of view you kill diversity. I remind you that the next fad you (and I) will be trying to catch will be created by a guy bothered by the current state of things. Bothered enough to act (and reunite the "Tipping point" conditions).
This guy attack RoR, he's attacked personally as trying to sound smart. Have you ever criticized anything ?
