Shared this earlier today on Google Plus (G+). Since it's easy to embed a G+ post in a blog, and because I want to keep this one for posterity (could be interesting to look back on a few years from now), I'm posting here as well.
The videos linked below seemed more balanced than some I've viewed on this topic. PBS NewsHour did a nice job working to cover different sides of the issues in an unbiased manner. Hoping for further insight from the upcoming twitter chats.
