I put together a short presentation about Bitcoin, how it works and why it’s there. I may eventually get around to fleshing it out, adding video explanation and notes. But for now… Bitcoin for Noobs.

I said I wasn’t going to jump into the buzz machine to talk about Google+, but I think the broadcast model used here is pretty interesting. I made a comment in response to someone wondering “How do I post something on your wall”. This is the Facebook paradigm which takes a graffiti approach to sharing information publicly. While you can “tag” people within your status updates (which is a relatively recent addition for Facebook) to draw their attention to your thoughts, you could also go to their wall and share your thoughts with them and everyone else who happens by (if they’ve set the permissions to allow this).
