I found a really cool time waster

Yesterday, a post at one of my favorite parenting sites led me to the greatest time waster ever! Have you seen this? Make your own bookshelf! Books you have read, books you are reading, books you plan to read. Why, you ask? Because it's cool. And fun. And I wasn't terribly busy at work. Check it out: http://www.shelfari.com. Here's my shelf: http://www.shelfari.com/tobyedavid. Isn't it cool?
