"The 90-9-1 Rule: In social media networks, 90% of users just read content, 9% of users contribute a little content, and 1% of users contribute almost all the content." What percentage of people started typing something, deleted it, started typing something else, then gave up when they realized they had nothing of value to contribute or out of fear of rejection?
This reddit post, invocatively titled Most of What You Read on the Internet is Written by Insane People, builds up on that rule.
