There have been several well-shared stories over the past few weeks about the origin and subject matter of material passed through blogs and Twitter. Above is a good data viz on the topic. Best I've seen, actually.
The blog side of the viz seems to make sense and is probably what most everyone expected: fairly well-rounded subject matter sharing with Politics/Government in the lead.
But on the Twitter side... It's amazing how much technology overtakes the crowd. So for those of us who stream technology and other stuff, perhaps we should try to step up our streaming of the other stuff.
