Comments can be blog posts
This person has it exactly right, (as I mentioned on Twitter). Comments are just as important as blog posts, because they basically are blog posts, just responding to an article. A good commenter spend just as much time forming their comments as a good blogger spends forming their articles, and both can contain great information. I think that news aggregators should allow comments to also be listed, and that you should be able to have all of you comments you write anywhere on your blog, with a link to the article you are writing about. I defiantly think if we could find all of people's comments on their blog, it would help centeralize their content.
