wrong comparison, I guess...
I'd consider a blog being similar to a newspaper and comments being like readers letters... unsuitable for discussion between blogger and different readers to each other...
bloggers writing crap are simply ignored, tooters writing crap are spread through federal and local timelines to hundreds of thousands like on Twitter.
Such crappy tooters will block replies requiring hundreds of thousand to take action by blocking/reporting... happy times for mods
