On most wikis, pages have "talk pages" to talk about the status of the article or debating over whether the article is necessary (or has unnecessary stuff). On the newer wikis, like this one, the talk pages have been replaced mostly by comment pages. And recently, the comment pages have been full of opinions and stuff.
So, I'm not demanding, but I think the comments should be reserved for debating over the page, not for opinions. You can leave that to the blog posts.
