I saw this post on Boing Boing today. Was particularly interesting to me because I had been selling various US publishers on how cool Penguin UK's million penguins experiment was all week long.
From Boing Boing:
"Oort Cloud is a new "social publishing" experiment for science fiction. Authors put their work online for critique, improve their work, participate in discussions, etc."
Aside from the community forum and feedback, all the geek goodies are there, including tag clouds and RSS feeds.
Looking for some more info, I checked the "about" section and discovered that I used to work with one of the guys running the site. Best of luck to you, Rick!
