I do agree about the importante of ‘flossing’ twitter. There is already a free alternative, http://laconi.ca, the system that powers http://identi.ca.

About making money with producing content, I remember a former email discussion we had upon your interview to Época magazine (big pt_br post + comments here: http://efeefe.no-ip.org/blog/processos-criativos ), with little conclusions. I still think we shouldn’t think in terms of ‘content’, objectified and tradeable ‘pieces’, but in information (and consequently money) ‘flows’.
One of the problems I have with easy licensing schemes such as CC is that they don’t change that relationship fundamentally: ‘authors’ and ‘content’ are still the same as they used to in the 20th century, and that perspective is just not useful anymore.
Of course, thinking in terms of flows raises a lot od new questions. For instance, objectifying things makes control easier in a sense, in that it creates interruption once you have finished making use of the ‘content’. The album is over, let’s get another one. In thinking of flows, that just does not happen. And people object to change, as we have seen two weeks ago when last.fm threatened to force non-gringos to pay for subscriptions to listen to their radios.
Anyway, I agree that we haven’t found definitive answers to those questions yet. Let’s keep on looking for/making them…
