I just came upon a fantastic and very active PID blog with tons of great content - please take a moment to check it out. Looks like it is filled with a lot of relevant PID info, and is being updated regularly.
http://www.impactdesignhub.org/ Along with all the great content, it also provides a link to a helpful primer on how to write a good blog post - if you are interested in making posts to this KnowledgeNet page, perhaps you can take a look at this link and get some useful tips:
