Jay Fitz, correctly, I think, takes on Bryan Person for his sweeping pronouncement about what makes a blog a blog. But Bryan's point about comments, however artlessly made, is valid: comments are a big part of the blog conversation.

Which raises the question, why don't I have comments? Well I used to, but the comment spammers attacked (like this) and my provider reacted by changing the permissions on the directory that made them function (before I got a big bandwidth bill.) And I just left it at that. Obviously I could have installed spam blockers and set up moderated comments, but unfortunately I don't have a whole lot of extra time to do all that.

Are comments critical for a blog to be a blog? Obviously not, as Jay points out. The discussion about comments vs. no comments has been going on for quite a while in the blogosphere, on blogs with and without comments. So yes, I agree that the blogoshpere is about two-way communication, but I also agree that you don't need comments enabled to participate.

See? I'm (we're) doing it right now.
