Visited the Web 2.0 Awards and the winners are -
1/ www.lulu.com - where I could have my secret manuscript published and feature on Lulu's site . I don't need to send it off to hundreds of publishers.
2/ LibraryThing - where I can see who likes what I like in the bookworld .
3/ farecast.com - a great site if you live in the USA - it predicts domestic fares and refunds you if they are wrong and you pay too much for your ticket. A boon for regular flyers.
