Oh, I know that we are supposed to work organically most of the time, but having traffic that can “see” us is essential, otherwise we can have the best material and it will be irrelevant if it’s not seen by enough eyes. 
That’s where advertising and affiliate programs are useful, to bring traffic. When you’re a larger business, you can get ad networks to show your ads and only pay when they convert, but when you’re small its not possible.
Patreon might also attract publishers with your own affiliate program, since you’d be paying publishers a revenue per action (% or bounty per paid patronage). If you spend 3 dollars on average per new user, but you make 5, you’re profiting. That only seems possible when your ads are on a cost per action basis or if your product is expensive enough to cover regular CPC marketing costs (the latter is just “impossible” with small value subscriptions, since you’d need hundreds of dollars per transaction to afford CPC marketing profitably).
Converting existing followers is something that I actually do that’s very effective and free. Prospecting new followers is very costly and even social media is designed in a way that forces you to “pay to play” or they will bury your content to not be seen even by most of your following.
Organic traffic from Google is the best thing we have access to freely, but there’s only so much traffic that they’ll send to you if you’re small, plus they keep changing their platform to hold traffic on their own site by showing snippets that already answer questions, for example. You can block that, but then you won’t show on searches.
We (creators) can surely use more traffic.
Publishers can use a good quality affiliate program that lets them add links to your creators that produce content related to their blogs and be paid with a recurring commision when a user becomes a patron.
If Patreon gets in the middle and provides that service, it will surely grow substantially in audience and revenue, since there’s no competition in the market and you’d be the first company linking creators and publishers (and ad networks through CPA ads).
I strongly believe such a system would benefit all parties involved and I wish you can implement that before the competition does.
