Its most precious resource, followers, is distributed far more unequally than wealth. In my sample, the top 1 percent of accounts has 72 percent of the followers. The top 0.1 percent has just over half. It is much, much harder to get to a million followers than it is to make a million dollars. There were 300,890 people who reported over $1 million in income to the IRS in 2011. Right now there are 2,643 Twitter accounts with 1 million followers, worldwide. Perhaps half are in the United States. Being an American with 1 million Twitter followers is roughly equivalent to being a billionaire.
