This document discusses using blogs to develop a personal learning network. It defines blogs as a contraction of "web log" that allows for spontaneous expression of thoughts online on almost any subject. Blogs can be personal, professional, or a combination of both. A personal learning network is an informal community that allows for reflection and lifelong learning through synchronous, asynchronous, and semi-synchronous engagement. Blogs are well-suited for semi-synchronous engagement as they can be updated in real-time or asynchronously. The document provides tips for using blogs effectively as part of a personal learning network such as being consistent, thoughtful, authentic, and engaging with readers while avoiding violations of privacy or responsibilities.
