This is just the coolest thing I've seen on Twitter in, well, maybe ever... (Scroll down for the earliest Tweets) Here's the tweet from @Harkaway that started it all: Hundreds of people then began tweeting away micro-stories in the enigmatic, endless City of Urm. And the city actually kind of came alive, with people adding in multimedia to their tweets, some people grouping together to form short but coherent narratives, and others popping by to add mysteries, histories, and revisionist histories. There are conflicts, sure, but they somehow work together. Urm is, after all, impossible. The talk of a shared universe in World Building reminded me of this gem. As a game and a writing exercise I think it's brilliant. As a way to put yourself out there in the screaming Twitterverse I think it's got an edge too. Besides just sharing Urm, I'm wondering what kind of crazy cool promotional things any Scribes (or other authors) have done on social media. Has anyone used Twitter to make some bite-sized reading for their WIP? Would you do something like this?
