Thanks to both of the ladies for posting the links.
I'm definitely in the 'keep it simple' camp. Kids would love for me to do stop-motion videos but they are time consuming and not worth my time. My regular videos might seem low-budget but they are still taking me 5-6 hours each to produce. I have been improving my editing, using B role, and multiple cameras whenever appropriate.
Regarding MCN's, as far as I know, most of them are not profitable. From my experience and from continually becoming educated, MCN's are only interested in the largest channels so that they can get larger advertising deals.
YouTube continues to desire to have higher quality content. That doesn't look like it will be possible with the less-than-TV advertising rates that exist on YouTube. What is curious to me is that I subscribe to a couple late-night TV programs who put snippets of their shows on YouTube. I rarely see ads on those videos. Sometimes if a star appears for an interview, there will be a placard at the end of the video promoting that program/movie/content. I wonder if those TV programs are getting paid from the program that the star is promoting.
I also wonder if YouTube has some sort of revenue agreement whereby if those late-night TV programs provide content for YouTube, YouTube pays them.
Finally, with YouTube's Music Key monthly subscription service, that opens the door to a YouTube Video monthly subscription service so that viewers have an ad-free option. When that happens, creators are likely to earn more per view than they are currently and they don't have to worry about whether ads are showing on their channel or not (monetization rate).
