Logically I can't wrap my head around your position. Content, like comments is just the output of someones thoughts. The majority of comments are short off-the-cuff statements, but articles on websites stand a better chance of having gone through a process of deliberation/research/etc. Perhaps you could argue that most content is fluff but even so, all I'm saying is that it stands some chance, versus no chance of being thorough.

So.. to me, the opposite holds true. If lets say I was interested in reviews on some technical product I wanted to buy - I would definitely prefer to have a lengthy article that goes over all the details rather than a comment thread which might detail one tiny slice of their experience with the product. So maybe if enough people comment, I can waste some time reading them all and cobble together a larger slice in my head, but again, its tedious, its just easier to go to a single source that has already done it.

Maybe what we really need is better curation than the current voting model.
