Jeff Croft writes about creating Lendle:
About a month ago, I got a call from Brian Ford, who happens to be my cousin. Brian’s wife, Carolyn, had come up with an idea and Brian wanted my thoughts. Amazon had recently rolled out a new feature that allows users to lend Kindle books to others using their e-mail address. This, in effect, means you can really only lend books to people you know (because you probably don’t know many stranger’s e-mail addresses). Carolyn’s idea was simple: what if there were a site that could hook you up with a stranger that has the book you want, so they can lend it to you?
I’ve been using Lendle for about a week now, and it really is fantastic. It’s well designed and makes it simple to lend or borrow Kindle books.
