My support of the KnowledgeBoard blogroll has several effects.
First, it helps to discover new interesting blogs. For example, recently I discovered Jerry Ash’s Plain Talk News, which led me to Association of Knowledgework (AOK) and drafts of their book on personal KM.
Second, it gets me involved into all kinds of discussions about “what blogging is” and “how to do it”. I started to collect them these writings in Better Blogging collection.
