In case anyone wants a more immediate alternative to Patreon, you can pursue a patronage-style system within Gumroad via it's subscriptions, with caveats.
(The biggest one IMO being you have to provide something in return, so traditional Patreon $1 subs don't really translate here)
This is an article on Gumroad's blog from someone who was able to do that, and talks about the pros and cons - http://blog.gumroad.com/post/169307494778/a-patronage-model-with-gumroad
