2013 Social CEO Report: Are America’s Top CEOs Getting More Social?

We did it again. After searching for each and every FORTUNE 500© CEO on four of the major social networks, we found out not only which chief executives are actually using social media—but how they are using it.

Here is what we found:

• Almost 32% of CEOs have at least one profile on some social network
• The average growth in Twitter followers for CEOs is 68.8 per day (but 838 per day if you include Warren Buffett)
• Two of the major social networks are gaining noteworthy traction among CEOs… Can you guess which ones?
