But Participation Inequality doesn’t limit itself to on-line interaction. I doubt that 10% of Coke drinkers – maybe not even 1% – have ever bothered to write the company, for good or ill. And the number of people who actively campaign for a cause are a small portion of those that vote for it.

(Not to mention that those that vote are only a fraction of those that register, and registered voters are only a fraction of eligible voters. If only 55% of the country can even be bothered to care who is going to run their lives for the next 4+ years, how can you possibly trust their opinion on whether or not Spider-Man unmasking was a dumb idea?)
