First time poster, because I generally have no reason to post. Anyway, I've watched all the videos. 2013 and 2011. It is pretty interesting. But then I'm the kind of person that is happy if I read a 300 page book and only found one thing of interest. I think there is a little bit of something for everyone at all levels. Some of it is very interesting and some of it is quite boring. But that is all in the eye of the beholder. I watched it over several days while I was retouching photos, so no big deal. I spent the money on the video because I looked at it as doing research. Just like I visit this website.
