Tag creation/deletion criteria
Because of recent discussions regarding whether vague terms like
ground should be valid tag names or not, it is clear that we have no consistent rules here. These terms are about on-topic matters, but they are vauge and ambiguous and cannot "stand alone" without other tags.
In comparison, Stack Exchange and in particular Stack Overflow are super-strict about tags and particularly so when it comes to deletion of tags. They have a huge system error on the site where creating a tag is somewhat simple and can be done by a single person, but getting rid of a tag needs to involve some 10 to 50 people including moderators in a "burnination process". The criteria they use can be found here:
- Does it describe the contents of the questions to which it is applied? and is it unambiguous?
- Is the concept described even on-topic for the site?
- Does the tag add any meaningful information to the post?
- Does it mean the same thing in all common contexts?
A tag must fail ALL of those tests in order to be considered for burnination. In any case, the ultimate criterion for burnination is whether the tag is actually causing harm.
Codidact does probably not benefit from having as strict rules as SO - in particular it does definitely not benefit from making the same mistake as SO:
Deleting/renaming a tag must be as effortlessly as creating that tag in the first place.
Consequently, if we want a high bar for deleting/renaming tags, we should raise the bar for creating tags accordingly as well. Or otherwise the whole system will eventually collapse as it did on SO.
With that in mind, I think we can use the SO criteria as a basis and form new rules for tags here. I think perhaps the last sentence in the above quote is worth particular consideration - does the tag cause active harm, such as confusion or wrong use of the tag?
