David and I talk about Patreon periodically, and it definitely seems like an option, but I don't know exactly how much of a following you need before you can effectively launch one. I also sort of dislike subscription plans in general, though admittedly, Patreon is one of the less-abrasive ones just due to its purpose.
I'm not sure if it'd be a positive or negative type of pressure to need to release stuff on a fixed schedule...on the one hand, it'd make it harder to commit to other work or larger projects, but on the other hand, the structure would likely encourage me to release "some kind of fleshed-out content" more often.
Patreon also caught some flak recently about changing their payment model and making it less likely for people to do low-price donations, which seemed like a huge bummer, but I don't really know how that situation has developed since then (I haven't heard about it in a few weeks - maybe it's been resolved already).
I'm interested to hear other people's opinions about this - either about Pateron (or alternatives) in general, or about the possibility of a 2DArray Patreon page!
