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?
- Yes
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.
