Why is kbin so full of empty stuff?

I'm not asking to be snarky or anything... I'm subbed to plenty of magazines that I enjoy reading.

It's just that the front page has the "random magazines" section, and the top bar is full of a seemingly random list of unrelated magazines... and 99% of what shows up in these two places is just empty. They seem like magazines that were made as placeholders and have been sitting empty for 6 months.

These two spots seem like prime real estate that should be filled with useful subs; or at least that magazines under a certain threshold ought to be filtered out of these locations to keep them relevant.

Or am I missing something?
