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.
If it exists anyone can start creating posts for it. If it doesn’t exist, they can’t.
The worse part is when they put absolutely no love into it. E.g. there are some where the banner is just the original logo form Reddit, but stretched all across… With no description or anything.
