Chris Aldrich posted about an interesting knowledge wiki using Github as the storage of the original content and using Gitbook to render the content. I have a federated wiki instance I have been using for some topics. Chris Aldrich also mentions that his own site serves as a commonplace book, capturing information that interests him. I think this variety of tools and practices is good to see. I have used a weblog in the work environment as a knowledge capture tool, then migrating some content to a wiki. My main observation is a common one: you get out of it what you put into it. If you don’t do much, any tool you use will not be very helpful. If you contribute content on a regular basis, the value will grow and grow over time. Which will you choose?
