On the other hand you see projects making hundreds of thousands of dollars on
crowd sourcing web sites. Of course they have a lot of traffic...
I guess it's a matter of engaging your audience. Not that I claim to know how
to do it. Trisquel has had some success for example. Also, paypal makes a lot
of people queasy, me for one.
A lot of people are cheap, it's true. On the other hand online the marginal
cost is close to zero so I believe the equation can work out.
I think this is an interesting problem to try to figure out.
