Thanks for outlining useful arguments when discussing informal learning and social media. While I come from a family chock-full of lawyers, I often giggle at the outdated perspective that comes from legal departments - as if they can stop the winter from coming or the sun from setting! People share inaccurate information all the time, informally. The benefit of putting it in some kind of wiki/social media format is that the conversation is visible to even more people, who can correct misconceptions and add even more expertise. It's the best fact-checking around.

Thanks again for a great post!
