Why is there a tag called ? Can't you just not add any tags? What's the point? Can we delete it? It is basically useless. Why would you create a tag like that?

1 Answer 1


Questions become automatically when they lose their last remaining tag. This happens sometimes when a question is migrated, or when a tag is removed from the site as a whole.

It's useful, too:

  1. You can check the tag to find untagged questions (so you can re-tag them).

  2. You can create a filter that notifies you via email every time a new untagged question appears.

In other words, this tag helps you make sure every question is tagged. This is a good thing.
