The What:
So Instagram is planning to hide like counts on their app. They will be rolling this (feature?) out to a limited set of users on the United States only. Only the creator will be able to view like count of his/her post. After testing for a few days, the future of this feature will be decided. The rollout should start within 1 week.
The Why?
According to the CEO, they want to make the Instagram ecosystem less competitive and reduce their users' stress.
Conclusion
The like count is responsible for people's dopamine surge. So this step, though a healthy one, might affect many people's business negatively.
