Some people are unoriginal and just regurgitate other people's stuff. Some people aren't social or interactive. HOWEVER, some people (like Chris) are able to take a simple list of sites and craft it into a valuable resource. One with well thought out, and brief, explanations, and then a follow up with his community to ask for additions to the conversation.
We can all learn a lot from this one simple post ... not just from the great content but how it was written. Well done Chris![Sorry folks. This one was delayed because it was inadvertently sitting in my 'drafts' section. I'm calling this post "required reading" - including all of the referenced articles/posts]
