Maybe those plugin guys should start charging for their work, so users see their output as having financial value.
Geeks are a strange breed. We'll code our fingers off because it's fun. Seeing somebody use our code (they like me! They really really like me!) is better payment than dollars.
(So long as we're being fed and can keep the internet from getting shut off due to non-payment)
Call me shallow but I like some of the nicer things in life. And I want to buy a fast car too. If a hardware engineer can do it, is it wrong for me to want to do it ?
This isn't necessarily an open source thing, either. I'm not a part of an OSS projects, but I am part of projects that cost me money, that I see almost no financial return from, and that make me happy simply because people use them.
