Summary Box: Facebook users get more than give

FINDINGS: A new study from the Pew Internet and American Life Project finds that the average Facebook user gets more than they give. That means more messages, more “likes” and more comments.

WHAT’S BEHIND THAT: Facebook’s relatively small group of “power users,” who do more than their share of tagging, liking and uploading. The researchers found that about 20 percent to 30 percent of Facebook users fell into that category.

FEELING GOOD: The result is that it feels good to be on Facebook, perhaps better than life off Facebook, as people bombard you with positive affirmations.
