I am always exited when I find a new voice writing and thinking about KM. Jack Vinson, from Knowledge Jolt with Jack, pointed out that Ton Zijlstra writes about information overload in a long post in his blog. He talks about the volume of information and how to distinguish between a signal and noise. Blogs provide a good filter and allow sense making individuals to make sense of the noise and tell us when it is a signal. I, have a very tight seive, but I read lots of RSS feeds. I find I only comment when the signal resonates with me.
