Yup! Here's the interesting, counter-intuitive thing: 99.9% of blogs can be shit, but there are literally millions of blogs. So if you have 1,000,000 blogs, and 99.9% are shit, you still have 1,000 good blogs! If only 0.01% of blogs were good, you'd still have 100 great blogs- which is excellent for the public good. The same long tail effects appear on things like Wikipedia, too. Wikipedia on average might have say 10-20% reliability, because 80-90% of the pages are crap. But that's because most of those pages are really obscure. The 10% that are most observed- say, pages about chemistry and physics- are updated very regularly, even quicker that science textbooks. It seems that people are really bad at thinking about this clearly, probably because we imagine quality is a yes-or-no proposition.
