I've seen the rhyme tag around, and I haven't quite worked out what it adds to the puzzle.
At least to me, it only indicates if the puzzle is in the format of the rhyme - and that makes it seem like a meta-tag.
Given the criteria for when to burninate on main meta, it doesn't score very well in my opinion:
Does it describe the contents of the questions to which it is applied? and is it unambiguous?
- It is unambiguous, but it doesn't inform me about what the puzzle is about
Is the concept described even on-topic for the site?
- Kind of
Does the tag add any meaningful information to the post?
- No, most people can work out whether something is a rhyme themselves
Does it mean the same thing in all common contexts?
Now, there are over 500 questions tagged rhyme, so I'm not suggesting we get rid of it, at least not right away. But given that just over 90% of rhymes are also riddles, and precisely one puzzle has just the rhyme tag alone, I'm just curious as to why we have the tag in the first place.
