Earlier I saw a question which was tagged riddle. This tag seemed completely inactive, it had only 11 questions most likely each of which ought to be closed (looking through them).
I decided to go through and remove this tag from each of these questions, as this question suggests, and voted to close where appropriate.
Was this the correct thing to do? Should I have made a retag request to puzzle?
The (similar) puzzle tag has nearly 500 questions and states:
DO NOT USE - prefer constructive questions, or use tags that describe your question.
