Unemployed bloggers are apparently at risk of losing their unemployment checks (or at least having them drastically reduced) if they include ads on their blogs. That is exactly what happened to a woman named Karin, from New York, according to a recent Forbes piece.

The number of jobs advertised online in the U.S. declined in May by 13.2 percent from the May 2007 level, according to The Conference Board.

This is the third consecutive month of declines for the U.S. as a whole. The May decline saw 579,000 fewer jobs listed than in the same period a year ago. A total of 3.8 million job openings were listed in May, accounting for 2.5 for every 100 people in the labor force, down from a high of 2.9 a year ago.
