This document discusses social learning communities and their benefits. It presents 3 key theses: 1) Knowledge is best created and shared within a community, not individually. 2) For people, acquiring knowledge is a meaningful social process that occurs between those who understand a topic. 3) The natural way to create knowledge is through social collaboration, such as on an enterprise social network. Examples of how communities can form and share knowledge on a social platform are provided. Areas for improvement are also noted, such as a stable chat function and virtual classrooms.
