The Project for Excellence in Journalism is now tracking news discussions in the blogosphere every week as well as news coverage by traditional U.S. news media.

But the indices published this week are more interesting – while economic news overwhelmingly dominated traditional media reports, several other stories also caught fire with bloggers, most notably the vandalism of an electronic highway sign to read “Caution! Zombies Ahead!”
