*I regularly watch videos and read news posts that come my way, and the ones that interest me I post on my Twitter account (found linked above). Sometimes I label the tweet with a "Must See!" The media tweeted in this way has in some way struck a chord or given me insightful information above and beyond what I read normally, and I feel this information should be highlighted as such. For such tweets, I also feel I should write a little more then can fit in 140 characters, and so below is one such item with commentary.
