Watching the "If, as you live your life, you find yourself mentally composing blog entries about it…" meme spreading, I find myself with the thought: someone should devise a way of automatically tracking blog-memes and visualizing the results. Between Technorati, del.icio.us, and Bloglines, there ought to be a way to extract the information, no? I’m envisioning something like the TouchGraph Google Browser, part family tree and part network, with some way to show the direction of linking. You could make it display a meme’s progression over time. Then you could figure out the points where different sectors of the blogosphere connect — where the bridges between one interest group and another are.
It sounds a bit trivial (after all, nobody really cares who posted their "Which Tarot Card Are You?" quiz result first*), but I bet you could use it to investigate all kinds of questions about social networks, and degrees of separation, and small world theory, and whether Malcolm Gladwell is right about tipping points and the epidemic model of change.
Of course, someone with much more geek cred than I have has no doubt had this idea already, implemented it, and posted the results months ago. I just haven’t come across it yet. Which shows some of the boundaries of my own online social network. I’m not enough of a geek to jump from the lit-crit / humanities / operaphile sector to the internet-culture / technology / social-software / semantic-web sector. Not yet, anyway. (But I did re-locate the Google Browser project site after completely forgetting where I’d originally seen it, and I did so via a combination of hitting a few likely blogs and guessing at del.icio.us tags, which says something in itself about the usefulness of such networks for locating information even if you’re only peripherally connected to them, and I should really close this parenthesis now.)
Thoughts?
