Long story short: one-half of all proceeds, after fees and taxes, is donated to charity. So by supporting me, you also support many other people who need the help.
EDIT:
I have found that holding videos back for one week for Patreon: Early Access, is a bit too long for everyone else to wait. So I'm going to reduce it to 3 days. Thus, videos I put out on the 10th of October will go out on the 13th of October for everyone else. I think this is fair, rewards patrons with a bit of early release stuff, and doesn't irritate anyone who isn't a patron.
