I love to waste an hour just looking at strangers pictures.
I'm not kidding.
I know most people have Flickr accounts so their friends and relatives can keep up with them and look at their pics, but I like surfing Flickr just for kicks.
There are quite a few sites and blogs that deal with books. Mine is one of many. Through my surfing, I've stumbled across a couple of Book Sites that have really given me a lot of enjoyment and information.
BOOKMOOCH This is the best site for trading books. You give books, get points and then order books you want. It works out nice, because you get a book credit for every book you send. You also get points just for listing books and acknowledging the receipt of books. The only problem with Bookmooch is that there are more points than books. Most of the popular books have already been mooched, and you have to fill out a want list, and check it often, in order to snag the good books the minute they are listed. But, all-in-all, I love bookmooch.
SHELFARI Shelafri is like MySpace for book lovers. It's also a great way to keep an online journal of your books. There are groups and discussion boards to help you decide what book to read next. This is a must-have site for all book lovers.
