Currently, everywhere on the SE network, communities are limited to 5 tags per question:
However, puzzles can meet many different tag criteria and as such, 5 doesn't always seem right. For example, I'm currently writing a puzzle that technically qualifies for the lateral-thinking, knowledge, computer-science, word, acrostic, limerick, riddle and rhyme tags.
My first thought is to consolidate the tags to simply use lateral-thinking, knowledge, computer-science, word, and limerick, which will actually be my course of action today. However, I can only do this because of a few noteworthy points:
- The limerick tag implies that rhyming is used, so rhyme can be removed.
- The acrostic tag will be easily identified in most puzzles and can be removed.
- The riddle tag can be inferred from the post itself and can be removed.
This isn't always the case however and there have been a few (e.g. two or three) other puzzles I've created that I wanted to use more than 5 tags for. I understand that in most cases, if you're exceeding 5 tags, your puzzle is likely entering the realm of too broad and is likely to be closed; but, consider a puzzle with a few steps, for example:
- Decrypt a message.
- Solve a number sequence.
- Perform some mathematical calculation using said sequence.
- Use lateral thinking to prove something about the puzzle with said calculation.
All the while, the puzzle could include a rhyme, tell a story, and include some imagery as a clue. This would qualify it for the cryptography/cipher, mathematics, number-sequence lateral-thinking, rhyme, story and potentially rebus depending on how dependent the puzzle is on the visual clue. Albeit, that's probably a terrible example, but, I hope you get the point I'm trying to make there.
Now, I will add that I don't think that new users should get access to this feature right away, but instead it could be a privilege earned around the 500 - 1000 reputation point mark (perhaps even higher around the 3k-5k mark), simply because I can easily see the potential for abuse and gaming.
My personal recommendation is between 8 and 10 with preference for the lower bound.
Should we (and if we should, can we) allow more than 5 tags on questions?
