The teamwork tag is used in 151 questions and doesn't seem to add value to questions. Some of the questions with this tag should be closed, others would be just as helpful without this tag. The tag wiki states:
Groups of people working cooperatively to complete a task.
Hmm. Is this a candidate for burnination?
I noticed that the revision history for the tag wiki includes this revision, which was later rolled back by Shog9. I couldn't find anything on meta about this particular tag, but is there some reason this shouldn't be removed?
