I vaguely recall people dismissing CA before so I have my doubts about their efficacy, but it is a reminder that this is the age we live in.
This is interesting and all, but I can't help but come back to an underlying question: why are we so focused on what's going on rather than how to deal with it? I suppose talking about it is a step towards this, but I worry that we may lose sight of the ultimate goal. I read this article earlier today, arguing for a disease model for bad ideas (aka "someone discovered Snow Crash), but there's a good point here.
Assuming these kinds of analytics actually work (which is far from proven), shouldn't we be more focused on how to inoculate ourselves?
