The Meta Stack Overflow tag improvements is in use on 45 questions. In the huge majority of them it is being used in the sense of "this is something that should be improved on Stack Exchange" (i.e. redundant alongside feature-request).
I could only find two examples of it used in a more legitimate sense of "Improving an edit" - located here and here. Perhaps these two could be tagged with improved-edits or similar instead.
Either way the improvements tag seems to add nothing to question. Burninate it as a meta-meta tag?
