Information wants to be free because it has become so cheap
to distribute, copy, and recombine - too cheap to meter.
Stewart Brand
There's a Tension...
It wants to be expensive because it can be
immeasurably valuable to the recipient.
There's a Tension...
Stewart Brand
That tension will not go away. It leads to endless wrenching debate
about price, copyright, “intellectual property,” and the moral rightness of casual distribution,
because each round of new devices makes the tension worse, not better.
There's a Tension...
Stewart Brand
If you cling blindly to the expensive part
of the paradox, you miss all the action
going on in the free part.

Officially Curated vs. Crowdsourced Data
● Crowdsourcing generally OK for easily verifiable data● Officially curated data needed for comprehensive, hard to verify data, small
specialized communities● Crowdsourced data is only possible because of revision control.
