SPAM
From DM News:

Slowing the Flood
A recent survey by the University of Maryland says spam costs U.S. businesses $22 billion a year in lost productivity, while a Stanford University study says Internet users waste 10 full workdays yearly dealing with spam. I don’t know about you, but I find it hard to believe that people spend 20 minutes a day deleting spam from their in-boxes, writes editor in chief Tad Clarke. A few seconds here and there, but does that really add up to 20 minutes?

Well, folks, does it?
