A few efforts are underway to enable discussions in blogs—including both comments posted appending a post and those posted to another blog and linked via trackback—to appear as a discussion thread like those on a message board. Lee LeFever, author of the excellent CommonCraft blog, says he usually likes ideas like this. Not this time. “I believe that blogs and message boards are two different things and they play two different roles. To morph them together may take the power away from each.” LeFever’s analysis of the notion is worth a read.
