I just noticed that my blog post showed up as a comment under Jeff Jarvisâ€™ blog post on Huffington and the New York Times. This looks like a trackback feature, but I wasnâ€™t aware that WordPress blogs (which Jarvisâ€™ BuzzMachine blog also is) did that automatically. But it made me think about how nice it will be when we have a more widespread set of functions which enable comments elsewhere to show up in the blog comments of the originating post. Like here, where someone might comment in Jeff Jarvisâ€™ BuzzMachine post to the comment entry coming from my blog postâ€™s reference to this post, and that comment would also show up under my post, since it would be in essence a comment on my post. Iâ€™ve seen tools like for Twitter posts that reference blog posts (WordPress plugin, but that plugin didnâ€™t work for some reason). But this is a hopeful sign of the possibilities for continued conversational integration between all of the Webâ€™s â€œsocial spacesâ€.
