Feedback as fannish currency?

I read Reposting and You – a fandom etiquette discussion and as with other similar posts I largely agreed with the basic premise (nb I don't feel like arguing about it with anyone either way), but was struck by the statement "feedback is the currency of fandom" and the assumption that people primarily create (or at least publicly post) fanworks in order to get feedback, and that a typical reaction to not getting "enough" feedback (where "enough" is of course very personal and depends on context) is to keep creating fanworks but to stop posting them publicly.

I'm not arguing that this isn't true for most fans, maybe it is. But it's not true for me, unless I'm misunderstanding the metaphor or something.
