That is a really unpopular thing to say these days.
What I am finding is that there are lots of businesses out there making good money out of everyone else's collaboration.
There are many free contributions I make in forums and community groups and so on. To sustain myself in doing those things I need some money. If I make a valuable contribution I deserve some return.
Looking at ideas4all.com for example, users give away ideas. It is possible that some users may be recognised and people contract them financially to develop ideas.
To sustain any focussed group as a creative team I think it would be right that they consider how to make money out of what they do.
So, how could the creative team earn its members a quid?
