With his skilled steering of JPMorgan Chase through the financial crisis, calm demeanor, and deferential behavior -- Dimon hasn't rankled legislators who are trying to clean up the banking industry, and he was one of the few heavyweight banking CEOs who didn't blow off a high-profile meeting with Obama in December -- you might assume he would escape the blogosphere's wrath.

How it was done: Zeta's technology mines the online media landscape -- including millions of blogs, message boards, and social media posts -- and then uses algorithms to measure both the volume and tone of conversations about a given subject -- in this case, the CEOs of Fortune 500 companies. Rankings are based on the percentage of total chatter about a given CEO that is qualified as positive.
