The 1% Rules.
The Citizen's Marketer book posits a 1% online activism rule that gells with Jakob Nielsen's 1-9-90 rule that I cited before.
At the time, I argued that the implicit indifference of the silent majority was nothing to worry about and, of course, the Long Tail tells us that a 1% niche can be very profitable. So focussing on the 1% is a good thing.
And then I read today that the richest 2% of people own more than half of the world's assets and I'm not so sure.
