TechCrunch owner Michael Arrington already dominates the Valley with his top-ranked tech blog. Now his related personal blog, CrunchNotes, has its own following. Those who subscribe to the CrunchNotes RSS feed saw the above entry speculating about "bomb-like" sounds in downtown San Francisco. (Arrington lives down in Atherton, over an hour out of the city, so he relied on a friend's account.)

Nothing came of it — at least nothing's in the news — so Arrington took the post down. Maybe his friend realized she wasn't hearing real bombs, but was getting those tech-bubble-bursting nightmares.
