Chad Ochocinco has been named the second-most influential person on Twitter. He beats out Barack Obama and Oprah Winfrey.
Twitalyzer, an independent research firm, measured the “influence index” by how the user shapes and contributes to conversations on Twitter. This means they count the number of times the person’s Twitter name is mentioned by other users (including retweets), not just how many followers they have.
