So, I recently got a Kindle (which is great!) and found a website where you can lend and borrow Kindle books from other people:
http://lendle.me
I loaned one of my books (The Hunger Games) and am currently borrowing a book from another person on the site.
Amazon's current policy is that some e-books (if approved by the author or publisher) can be loaned out to another person, but only once. So if you loan your book once, then you can't loan it out again. Bummer. However, I don't know anyone else with a Kindle that has the same book interests, so this website allows me to loan out and borrow books I otherwise wouldn't be able to.
I did have to "wait in line" for a book, but only for about a day or two to get the book I wanted to read. There is also a policy that you can only borrow books if you loan out books. I think if you loan out a book you can borrow 2 books.
