Why are there no questions related to the vim tag?

Question

When I search the keyword vim on stackoverflow, there are lots of questions which are tagged with the vim tag, but when I click the tag named vim, I am surprised to find that no questions use this tag. What's wrong? What happened?

What's more, when I click vim tag, it leads me to a page named the Featured tab. What is this?

Is the vim tag useless? If it is useless, why this tag is on the site?

Answer 1

Your screenshot tells you exactly why - you are on the "Featured" tab and there are no vim questions with active bounty (which is what "featured" means here). Click "newest".
