A great quote, the kind that changes your mood or frame of mind, can come for a famous figure or your friend holding a beer. Qwotebook, a web quotation sharing project, lets you compile quotes and see and favourite others' quotatables.
The site hatched from the mind of Drew Olanoff, the net figure who started the Blame Drew's Cancer groundswell on Twitter. After signing up and logging in, you can add quotes you keep close, attribute them to famous figures, and dig around to find other quotes you like and add them to your favourites. The site's still in somewhat early development—no search yet, for instance—but makes for a neat place to stash the quotes that you lean on when times get tough, or when you're looking for direction.
