The company did some internal research and found that users, especially younger ones, were afraid to “Like” because of the implied endorsement. Less Liking, or sharing, means less interesting content on Facebook and fewer posts about what these users are doing.

But at Facebook’s f8 conference, the company will give developers the power to create their own actions.
