Diane Moon's got another good one about why what happens in the blogosphere matters.

Blogs won't replace traditional media. And yes, bloggers often take themselves much too seriously. But it remains that when misinformation is published, blogs have increasingly shown that they are a thousand times more effective than angry phone calls or letters. Because we help form a living record, one that can be checked and rechecked and potentially seen by countless people. Besides, people in the press are like anyone else; having one faceless person criticize you is one thing, but seeing your name or your publication all over the place in a publicly humiliating way is another thing indeed.

We're not the most important thing in the world. But we're significant, as are our readers, who are even more important.

Yes, indeed. Blogging matters.
