This articles are a few months old, but the first I had seen of them. I wanted everyone to be aware that YouTube content is now considered in the public domain for Fair Use.
Fair Use and public domain are two different things. Fair Use allows me to quote your writings in another venue under certain circumstances, and for certain purposes. However, under Fair Use, you still have rights under copyright. Public domain is the absence of copyright.
In the future, please post a readable article in addition to, or in place of, a YouTube video. Not everyone has broadband internet, and many of our users are behind workplace filters that prevent them from viewing the content.
