For each post, I'd like to display a list of its tags that are used by at least one other post. (That is, a tag shouldn't be displayed unless clicking on that tag will lead to at least one different, related post.)
I read through the documentation and searched the plugins page, but came out empty handed. (The closest thing I could find is a "related posts" plugin, but it displays the post titles instead of the tag names.)
Is there any way I can go about doing this?
