Inside Patreon, the economic engine of internet culture
Unless I'm missing something, they seem to only have a monthly contribution model.There are many times where I find a content creator helpful (for example a video tutorial on how to fix my broken washing machine), and I'd like to reward them.  But I don't want to do it monthly, as I'll probably never watch another thing from them. 
 So I'd like to be able to easily leave a one-time tip.Can Patreon do this, and it's just not obvious?
