Regarding the empty tag, I was specifically talking about a tag that I followed from a post. So it appeared at the bottom of the post, I clicked on it, it took me to the trending page for that tag, and there was nothing there. The post that I followed to that page should have been there, no?

I mean, I'm not sure. Those are all implementation issues in the UI code and different people have different principals and priorities. But it seems weird.
