My other stupid idea of the day is this. Take advantage
of the relative stupidity and inefficiency of search engines.
Put up a single page per book with no other information than just
the NY Times top 10 best seller, one book and title per page,
that comes out every week.
The natural sorting of the pages will usually find that page
more 'exactly' relevant at a higher percentage than pages
that have to include stuff like pricing and copyrights, etc.
Automatically forward to Amazon.com with the changed URL
with the forkrecommendedrA tag at the end.
Then just use the recommendation kickback to make the site
self-sufficient. Welcome the middleman.
There isn't a search engine alive that can outsmart me. 8-)
