Though I'm sure many of you have already seen this (in case you are not following Sam, aka
copperbadge's jornal) I thought you'd enjoy reading about the use of Livejournal to create/construct/collaborate about fiction.
copperbadge wrote, edited, rewrote and eventually self-published a novel, Nameless, and the following is more a review of the process (he posted each chapter on Livejournal during the editing process and comments/response from the enormous pool of readers really changed both the writing of the novel as well as its structure).
Trial and (Ex)tribulation: The New Face Of Authorship in the Web 2.0 by Rebecca C. Moore
The postscript to Nameless:
Talking with Twenty Five Hundred is a lengthier description and analysis of the crafting of a book with (literally) an audience.
I've read Sam's book at least three times in actual print (and probably once or twice on Livejournal) and I still really enjoy it. Reminds me that I never did finish
The Dead Isle. Guess it'll go on my list!
