This graph animation illustrates the reach over time of a blog post. When a blog is activated (when a node is selected by the pointer) other blogs that link to it have some chance of referring to the injected post. The animation is intended to give an impression of how information might spread in the blogosphere.
Firstly, I activate a few peripheral blogs – these don’t have many connections and so we don’t see much spread. Then a small community in the south west corner is activated – information spreads within the community but doesn’t break out. Finally I look at a few blogs in the central core. Here we see information spreading through the core.
Note that the graphical data is real – this is a visualization of the core of the blogosphere circa 2007; the spread of information is only a (simulated) illustration. Note also that there are many other (better) ways to model diffusion – I’ll publish more animations as and when I start looking into this area!
The weblogs that I use in this example are:
