You might be on to something there. I'm not sure how becoming multi-talented using photoreading is going to make you a weapon though.
I have thought about the bookstore scenario a little, and I wonder if in the future when photoreading becomes a more well-known and widely taught subject, that bookstores will have to be on the lookout for people doing more than just previewing a book.
I dream of having my breakthrough experience and finally getting everything I've learned about photoreading flowing, so that I can zip through my collection of 200+ books and then go on to the Barnes & Noble on the weekends and absorb every bit of information I want there.
