Some dude is running an experiment to see how fast news travels.
Read this then link to it if you are a blogger yourself:
Acephalous: Measuring The Speed of Meme: An Experiment in which You Will Participate, Or Else...
(The fatal flaw of this experiment may be that the link above is not actually 'news' so we're really measuring how fast 'experiment' travels. My suspicion is that the old adage is correct, in that 'bad news travels fast'est, followed by good news, followed by value-neutral junk like this. But we're game. The 'scientist' in question assures us his idea is not a chain letter, and since he's not a known republican we believe him. (joke.))
