Greg Laden, whom you might know from The Blogosphere, makes a good case that blogging about science, skepticism, et cetera, can actually help resolve long-standing questions a hell of a lot faster than traditional methods:
Someone is always wrong on the Internet. The idea that the most free-wheeling part of the Internet–blogs–would be a place where conflict is resolved seems laughable.
