A situation where bloggers jump on a particular story and work it to death, often making assumptions with facts not in evidence and often including heavy doses of FUD.
The technical bloggosphere had a nasty case of blogerrhea over the case of Psystar, assuming the company was a fraud.
When people just can't stop blogging. Even when they have nothing important to say, they just can't control themselves.
You know you suffer from blogerrhea when you let the world know when, where and how you took a dump today.
