Should politicians blog? Charles Kuffner and Ezra Klein are having an important discussion about whether it's a good idea for Gary Hart to be blogging. Personally, I think the only problem with Hart's blog is that it doesn't link to a certain other blog . . . But, more seriously, I think Ezra's right that controversy over political blogging can only be a good thing for Hart's potential campaign. Hart understands the significance of new technologies and their ability to transform political conversation. Also, I think the fact that he has a blogroll and comments places him squarely in the blogosphere. Compare Dean's blog, which looks more like a rolling press release. Bloggers are right to be giving Hart a lot of credit for taking this medium seriously.
