This comment is sort-of related to peer production
I didn't give it much thought when I set up the class web site and blogs, but I turned off commenting for everyone's blog but my own. I was worried about comment spam. But I've just noticed that an earlier entry actually attracted a comment from someone I quoted. Blogs are great that way. If we had commenting turned on, do you think Yochai Benkler would drop by to comment on this week's remarks about his work?
