Patreon is a website that can turn any creator (art, audio, video) into a monthly subscription. Think of it as a low cost, continual Kickstarter for someone you're a huge fan of. There are some gems hiding on the site in the form of comics from Michel Fiffe, Melissa Mendes and Charles Forsman.
When navigating Patreon's top comic creators the first thing you'll notice is the huge disparity between some creators "patrons" and others. Some established webcomic creators have thousands of people backing them amounting to literally tens of thousands of dollars per month. There's also a shitload of furries. Dig a little deeper and you will find pages for independent comic creators like Michel Fiffe (Copra), Charles Forsman (Celebrated Summer) and Melissa Mendes (Lou).
