Am I the only one that's tired of the absolutist arguments without any substantive evidence that seem to plague social news sites?
We have no idea if Y Combinator's "No Idea" thing is good or bad. I suspect YC doesn't know either and once they do, unless they let us know how it worked out, we still won't know. No amount of prognostication will answer the question. It's a real pet peeve of mine when people who don't know what they're talking about not only answer questions, but go above and beyond that to answer them definitively.
The only mistake you've made is submitting this as a comment instead of a blog post as it is clear that you can play these types of arguments out piece by piece on blog posts that will make it to the HN front page.
