More new Web 2.0 services!!!!

I browsed Web 2.0 Awards and Webware and I found some interesting websites that I want to go and browse more deeply. I need to explore more Books category so see how we can use all new technologies in our library.
I found Reader2.com is more interesting then LibraryThing beacuse they have more Readers options and English + 12 other languges (Russian and Ukrainian too!!!!) to browse. WOW!!! You can publish your books by yourself with a little help of Lulu.com - it's really easy, I'm not a writer but if somebody ask I can recommend this website.
