This presentation from the MIrcosoft guy is mind blowing. Hes showing a live visual representation of the blogger sphere. We saw everyone who uploaded a blog mentioning Obama at the moment. And my god it was beautiful.
We just looked at a graph that showed when online blog attention turned from Hilary to Obama and it seems to have happened a month or so it happened in real life. Basically, the online data can be use to predict what may happen in the political pool.
There is a prototype program for following blogs and news. All of this will hopefully give politicians and now people like us a better understand of how these tends work.
