There's something about April 1st that brings out intesting stories that are too outrageous to believe.
Seth Godin was ready to be one of the perpetrators on this April Fools Day, but decided not to pull his prank. I suspect it's the after-effect of him getting slammed several times this year for things he wrote that weren't hoaxes. He weighed the benefits of pulling off his joke against hate mail, mainstream media condemnation, and other possible repercussions, and he pulled his punch.
Still, it was a pretty good hoax - a blog tax, with a special dongle required by U.S. Homeland Security before people could post their items.
Hey, did you see the story about Prince Charles making an ass of himself? That's not a hoax. He really is an ass.
