I agree - there are plenty of empty magazines setup as subreddit clones. What we really need is a push encouraging content and comment submissions more than anything else. That's what's going to drive the development of a vibrant community on kbin.social.
Generally, unless you have at least 20 pieces of content from multiple users with active commentary, most folks will assume it's a dead community and move on to a bigger community on lemmy.world or similar to find more content. One thing I would suggest for the moderators of growing communities is to always comment on, upvote and boost your contributors' submissions in the beginning stages of community growth. Your personal engagement of the content is the first step in encouraging your readers to do the same.
That being said, I'd love for folks to create more new niche communities that didn't exist on Reddit. There's a lot more freedom here - we should take advantage of it.
