Ok, so this isn't exactly web 2.0; but if we are considering ways for organizations to spread information and ideas and possible make some $$ along the way, I encourage you all to check out BookSense.com which has an Amazon-like affiliate program where you can put something on your website, blog, etc, like "Books we like and think you should read" and get a commission if someone buys.... here's the kicker... you're actually supporting local independent booksellers.  One area where this can really be handy is around environmental education.

From their website:
"When you visit a BookSense.com virtual bookstore, you will experience the knowledge and passion of independent booksellers who share their love of books with their customers and their communities. You'll have access to information and news about local authors, store events, and myriad staff recommendations -- and you will also be presented with content that reflects the collective wisdom of booksellers from all 50 states and Puerto Rico."

Enjoy,
