I just had an idea - a comedy blog called The New Adventures of Jesus. Bear with me. Basically, it would be about Jesus coming back and documents the things he encounters - things like self-righteous Christians who treat him badly, and him laying into idiots who follow the exact word of the Bible. It would be very cynical and likely offend a lot of people. Anyone like the idea?
Another idea I had recently was for a collaborative science fiction novel, written as a blog with each chapter being submitted as a blog entry by one of a number of authors. It'd be a near-future cyberpunk type thing. If anyone else likes the idea and would like to participate, I might look into it further.
So let me know if you like either idea.
