As a YouTube content producer, I am almost totally reliant on Google/YouTube's good grace to send me a payment every month. If, for whatever reason, Google changed its policies such that I could no longer earn money from these videos, I would be out on the street in no time.
To mitigate that risk, I'm considering creating a "premium" channel which would be subscription based, delivering an extra layer of high-quality video content and two-week advance access to my regular content.
If you would be one of those who would subscribe to such a channel, please say so -- and give some idea of what you would consider a fair annual subscription fee.
