On the one hand, I understand the concern. "The lack of discussion and further conversation is something I have missed from the blogging experience," writes Tom Barrett. Blogging is still a valuable forum for reflection, he writes, but "whether we care enough about other blogs is another thing." Maybe. But as Phillip Cowell replies, "My best read post was on uses for Minecraft - over 1000 tweets and FB likes. 0 comments." Me, I don't think it's a big deal. People read an academic paper and then discuss it in a classroom or hall, and you never see the discussion, but it's there. To me, the ideas are what matter. And all forms of engagement (or non-engagement) are legitimate.
