This may or may not be interesting...buy why do I have to spend 20 minutes watching a video to find out, when the same information could be conveyed in a written format that I could read in 5 minutes, or better yet, scan in 1 minute to get to the punch line or decide if it's worth reading in detail? This is a general complaint that I have. Why is so much information now presented in video format rather than writing?
