Swine flu on Twitter

By now, you've heard about the swine flu. The news is pretty much everywhere. That includes, not surprisingly, Twitter, where thousands upon thousands of tweets mentioning the emerging virus are being sent. A lot of these tweets simply provide links to mainstream sources of news and information. And, of course, a lot of them are filled with misinformed nonsense, from conspiracy theories to warnings about pork.
Given Twitter's rising prominence, that has some criticizing Twitter as a cesspool of garbage information. But is the criticism deserved? Yes/ no?
