I find this one fascinating: The Book Depository Live. Watch in real time as people all over the world buy books. Why I should be mesmerized by seeing someone buying Neil Gaiman's Anansi Boys in Sweden, I don't really know. It's the magic of the WWW.
And a link for Shakespeare buffs to add to their bookmarks: Shakespeare and Film: A Microblog. Great source of news on new and old movie versions, dvd releases (including David!! Tennant's!! Hamlet!!!), and useful YouTube clips.
