Tumblr explained. The 1:9:90 rule aka “Nielsens Law” of social networks. Which are you, hipster underclass sharecropper?
* 90% of users are the “audience”, or lurkers. The people tend to read or observe, but don’t actively contribute.
* 9% of users are “editors”, sometimes modifying content or adding to an existing thread, but rarely create content from scratch.
* 1% of users are “creators”, driving large amounts of the social group’s activity. More often than not, these people are driving a vast percentage of the site’s new content, threads, and activity.
