Hmm, so basically Paypal donations with a Patreon-esque look, eh? It's interesting and I've seen people using this a lot more lately.
I'd be curious to read about people's experiences with this, like if they get more one-shot donations through this than with Paypal for the nice interface, convenience, and apparent ability to leave a message. Even if Ko-Fi takes a bigger cut, it might make it worth it?
