Here is a useful list of knowledge management blogs to start the year. It includes three categories: general knowledge management, Web 2.0 and content management, and collaboration. The list from Biz-gasm offers a brief description of each listing so they took some time to get to know the sources. All the ones I know on the list are excellent and I learned a few new ones to check out. Of course, there are other great ones relevant to KM that are missing such as Euan Semple, Gautam Ghosh, Megan Murray, Samuel Driessen, Bertrand Duperrin, and Mary Abraham but this is a nice start.
Many of the blogs on the list are included as content sources for the Darwin Edition on Enterprise Social Media since that target content also covers knowledge management. I learned a few new ones that I added to the content sources. The Darwin Editions provide a way to efficiently monitor the conversations within a target set of content.
