I found example of Ankesh's nice quick profit idea about parodies of popular products.

Is there a bigger popular product out there than Harry Potter?

Fans are chomping at the bit for the next Harry Potter to come out.
But to wait for the next one is unbearable and since there's no
Scooter Libby inside the J. K. Rowling inner circle the prospects
look dim until summer time.

So why not write a book about what will be in the next Harry Potter book?

According to Publisher's Weekly that's exactly what a group
at mugglenot.com have just done.

Titled...What Will Happen In Harry Potter 7?

It's 214 pages of pure speculative about HP7.

I think this PPP is a great QPI that could be applied
to many other products.


Here's another QPI for PPP's.

Again according to PW teen book sales are booming like never before.

What are they buying?

More grown up themes.
According to PW this is a global phenomen by the way.

(Could this be a twisted positive link to the recent negative one found between overweight kids and early puberty?)

Anyway since kids are buying mature books what about
more business building books directed toward young adults?

Something to think about I guess.
