The blogging equivalent of the wave

In looking at the Obama blog I’m noticing people doing a blogwave, basically posting one letter and then trusting the next person to spell the next letter and so on. Usually Yes We Can!

Has anyone seen this before on a blog? It’s a really interesting method of trust and connection through fun + vulnerability in a digital space.How’s that for analyzing the crap out of something fun. It’s like analyzing a joke, I know.Â
