why do people register new communities and then not post content on them?
I see lots of communities with hundreds of subscribers, but no posts. What is with that? If you’re going to register a community, at least help it get going. Post some content regularly, until it becomes self-sustaining. It’s disappointing to open a community with hundreds of subscribers and not a single post.
Pretty sure it's due to a larger social phenomenon called the 90-9-1 rule:
The 90-9-1 rule is an observation-based rule that states that 90% of internet users are lurkers who read or observe, 9% of users contribute from time to time, and 1% of community members create new content.
