Wow - $4 million for a nagging website?

I am vaguely familiar with the FlyLady website. When I say vaguely I mean that I have heard of it and until today did not really know all that much about it.

I saw a story on AOL's front page today 'FlyLady Nags Her Way to Millions' and I was like what?!?

I read the story. Her site is such a simple idea, yet she's making millions off of it! That is insanity! I really wish I could come up with a simple idea that makes some mad cash like that. Who knew that people would pay to get nagged?

I must say though - $4 million is rather impressive for something that seems so simple.
