Well, a proper review of Bookmooch. I have been using it and I love it. But its not brilliant. Well lets get to the criticisms. If people put up books they do not have, get the 0.1 point for a 100 non existent books, they can exchange them for books on a deception. This has been done, when 1 guy in Asia did this and was finally stopped (I read this on another article, but can't find the URL, so sorry for that). There is also the look. It could really do with a cleaner look. Also (from the same article I can't find), what about an RSS feeder for when your wishlist book comes in.
The advantages are really good. The social element of swapping books, getting trust points from feedback and being part of a network, is its major selling points. As Cronin-Lukas of The Big Blog Company said:-
"Google sells reach. Amazon sells reviews. eBay sells reputation"
Reputation really helps on this site. People come back to my bookmooch as I have positive feedback.
I got to say, its a great service, but it can still add more features.
If I find the link i will post it up to that article I can't find.
