Anil's gone and put together a bunch of observations on how individual blogospheres mutate and evolve, as well as interact with existing blogospheres. Remember that weird program "Life" on your Tandy? Or how about your fractal-generated WinAmp visualizer plugins? Think that crossed with high school social interaction patterns. Related, and also on our recommended reading list (there will be a pop quiz sometime next week), is Niall Kennedy's Wikipedia entry on the history of Moveable Type. And since it's Wikipedia, feel free to fact-check!
