Web forum organizational question: there are Primary tags, and Secondary tags. You can put Secondary tags beneath Primary tags (they then only can be used within that Primary tag), or leave them “free-floating”, as it were. I’m currently leaning towards only affixing Secondary tags to Primary tags for things like Support topics, and leaving everything else free-floating. My reasoning is that you might be reading a book that’s about politics, and if I affix the Secondary tag Books to the Primary tag Culture and the Secondary tag Politics to the Primary tag News, you wouldn’t be able to tag your post both Books and Politics. Does this organizational principle seem sound?
