Site for reading, no downloads.

Does anyone know some good e-book sites where you don't have to download anything. I heard the library of doom was good. Does anyone here use it/know about it. Also any site recommended  shouldn't have only really old books plz thanks :)

www.gutenberg.org/ - over 33,000 free ebooks and you can open them all like regular web pages if you want. Just 'cos a book's old doesn't mean it's not readable or anything. For instance, this is the funniest book ever written:
