Apparently, reader comment feature is not popular among bloggers. Some evidences:
- While Radio supports it, many radio themes don't even show it.
- Most of blogs I visit don't use it.
- If used, I hardly see any comments.
I think there are two factors that discourage blog comments:
Etiquette – Unlike discussion forums like slashdot that convey the feeling of a public place or neutral ground, blogs are a part of someone's home page and convey the feeling of someone's home. So posting negative comments on someone's blog is like saying something bad to a party host.
Visibility – Blog comments are typically not displayed inline of a blog. Only indication I see is "comments [0]" after each blog post. Out of site, out of mind applies here. Also, "comments [0]" reads like an empty restaurant, not too inviting.
The reason I am poking into blog features is to identity the ingredients behind blog's popularity that I can apply in my groupware projects.
