Rich,
As stated above, what you have done in the world of editing is top notch. I can probably speak for most in saying there is no comparison in your talents with production and that of most YouTubers. Your very job was to produce good videos and of course that comes with good editing. YouTube however is not necessarily that. We don't go to YouTube for a "finished product" as we would if we were purchasing one of your videos or a "Black Diamond Railway". When we say a YouTube video is good we are mostly speaking of the author's intent, what information we received from watching the video, and most importantly how fun it was to watch. The very idea of YouTube is for one to be themselves and we are hardly perfect. Frankly the "imperfection" for some is what keeps them coming back. It gives others the feeling that they can do it too. Not to mention IT'S FREE!
I believe you see the videos through the eyes of someone who has mastered the art of production but most of the content producers have not seen a day of edit training and production. They simply want to have their chance to be seen, heard, and get their chance at being in the limelight, even if it's only for 20 other people who watched their videos.
