Fiction by way of diaries - it's been done before, eg Adrian Mole, Bridget Jones. My idea was to have a collaborative project with the story evolving in real time via the diaries of a few main characters (published in LiveJournals) - each one written by a different author. You'd need a fair amount of coordination between the writers and plenty of advanced planning of the plot, but if done well it could be really cool. You could have the story emerging over weeks or months, multiple viewpoints, updates appearing conceivably several times a day.
There you have it - well, the structure, at least.. Just need a plot & some characters... Other thoughts - You could do it one of two ways:
- The LJs really are LJs, the "characters" read and post in each others journals - could be fun, but scuppers the idea of reading the characters' private thoughts
- The LJs are the contents of the characters' private diaries, characters are not aware of what the others write - I reckon this would be the way to go, plus readers can post comments on the diary entries, etc.
