I don't know if you saw it, but it was around for a while. It's probably still going..
Anyway, I'd question this.
It sounds like a project to infer what people are reading to me.. there just seem to be so many 'human network' experiments going on at the moment. If you have a web log, and syndicate it, you will have noticed all the stange machines trawling for your feed. What are they doing with them?
