Clay Shirky on why email stuffs facebook et al

I interviewed Clay Shirky earlier this week. Here's part two of the series.

(part one: How algorithms caused the credit crunch)

In part two Clay explains why he thinks email is the most effective tool for group-forming (and therefore for influence on social and political change) right now. He describes the impact its 'dull' ubiquity is having on the US Presidential elections.
And we talk about the future of mass any-and-everything (though particularly broadcast TV) with reference to solidarity goods (value gained from shared experiences). Clay reasons that far from dumbing down, the fragmentation of the internet is demanding increasing quality from its hits.
When media and channels were scarce you got a share in the value of solidarity goods simply for showing up. Now you only get a share by being truly excellent.
