I'm debating right now what my next book will be about, but I've already got some good ideas percolating. No it won't be social media magic...though that could be the name of a chapter.
Anyway, I've been playing around with my Facebook Timeline, adding some events to points in the past, mainly where I moved to and where I've lived. I wish they would let you create future events on your timeline, but it doesn't look like they do. However the possibilities of using an FB timeline for a bit of retroactive magic does excite me, especially when you can add pictures and videos to a specific date in time. You can graphically rewrite your timeline and make it into a very creative experience.
For example I've added several fiction events to my timeline. I've done it for the sheer humor of it, but there's nothing to say that you couldn't go in and rewrite portions of your life with modified details, and use that as a kind of narrative that also retroactively rewrites your life. And if you can get people into participating with you via tagging, you can even come up with some clever meta events.
It's really about having fun, but also getting creative with your life. Changing what happened on the timeline might open up some possibilities for you, or if nothing else give you closure on events in your life. It's something I'll keep playing with, as much for whimsy as for any magical purpose. The time line is a graphic and textual narrative of your life. It can represent where you've been, who you've met, what you've done...and it can part fact and part fiction. FB probably wants it to be all fact, but why make it all fact?
What about you? How would you experiment with the Facebook timeline?
