There have been a few good, funny uses of facebook/twitter/youtube and etc. to retell various religious stories in the past year, starting with Nativity 2.0 (I think) on YouTube, and continuing through this past holiday season with a seder in facebook format (which apparently the writer did last year as well), and a facebook format version of the Passion. The last features Lewis and Tolkien as facebook users commenting on the story as it transpires.
It's a little large, but I think quite clever. There are a few of the "users" I'm not familiar with, Bart Ehrman in particular, so others may appreciate different jokes than I did.
(If you're interested in any of the other internet memes I mentioned, I'm happy to share them off list, but didn't want to clog up the group with lots of links!)
