The Great American Novel - we all dream about writing it, but who has the time? Maybe it would be a little less daunting if you could work on it 140 characters at a time. The Twitter Fiction Festival gets underway today. Would-be authors from around the world have been invited to share their stories and, possibly, give a new twist to the written word.

Pulitzer Prize winning author Jennifer Egan experimented with a short story for The New Yorker earlier this year made up entirely of tweets. She'll join The Daily Circuit Wednesday to talk about her project.

Erin McKean, self-described "dictionary evangelist" and founder of, will also join the discussion.
