I know that this isn’t a new idea, but itsallinyourhands.com is a really neat implementation of the viewer decided plot line. It is sort of a choose your own story. Viewers vote on which way each plot point will go, will he skip the date and go for the sex bunny or will he go on the date with the shy girl. The viewer decide.
It looks to me like the shows on the site are very well put together. The editing is pretty good and the acting is not bad. This could turn into an interesting way of building an audience.
