Well, the title says it.
The legal tag has two questions. They're asking whether something is legal. They're not otherwise related.
Moments ago, I removed the legal tag from the question Is license required to sell songs replayed on a virtual instrument? There's a music tag, which it should have been tagged with to start with.A great deal of our questions ask whether something is legal or not; this doesn't mean they should be tagged as such, because whether or not something is legal should not determine whether or not users are able to answer it.
This kind of tagging is not useful for categorising questions, at least for our purposes. It doesn't help users find questions, at all.
For the above reasons, my proposal is that the legal tag be removed from those two questions and then the tag blacklisted.
To be clear, this does not mean that we will not be able to have tags containing legal
. Tags must just not consist entirely of legal.
Additionally, I would like to propose that we pre-emptively blacklist legality, as it would fill that void, and I don't see it being desirable for the same reasons.
As an aside, analogous debate has emerged recently on English Language Learners regarding the grammar, which is almost exclusively used as the "default" tag for users who don't know any better, and for questions on whether some word, phrase, or sentence is grammatical. It's not really useful for categorisation, either. Except it's on over 4,000 tags, and removing it is as much of a problem as keeping it.
Let's get ahead of this here, and encourage useful tagging that actually benefits future users of the site.
Does anyone see any utility for these tags not addressed above? Alternately, does anyone wish to discuss anything proposed here?
