I recently found out that Meta Stack Exchange has a groups tag. It has 9 questions and no tag wiki or excerpt, and really doesn't add any useful information to questions. On most (not all) questions, groups can be replaced by stack-exchange or notifications.
Should we burninate the groups tag in place of more useful tags, or am I missing a reason to keep it?
(While there are just 9 questions with [groups], I don't want to remove the tag from all of them and then find out that the tag should be kept, thus I'm asking this question first.)
