Over the last couple of weeks I've been quietly waging war on the unit tag.
unit is one of those troublesome tags that is highly ambiguous on it's own, and needs to be replaced with several other more specific tags. I've re-tagged all 200+ questions that made use of unit, with almost all of them falling into one of these three camps:
- unit-testing (questions pertaining to unit testing of code)
- units-of-measurement (questions pertaining to height, weight, distance, and the like)
- unit-type (the small quantity of questions pertaining to the unit type concept used in functional programming). For this one, I've added the unit-type tag and a starter-for-ten tag wiki.
Request: please can we now blacklist unit?
- There are no sensible tag synonyms for this ambiguous tag.
- It keeps coming back (I've dealt with a trickle of new questions tagged unit), all of the recent ones being examples of where users have typed "unit testing" into the tags list when they mean "unit-testing".
- The tag wiki for this tag has contained a "Please don't use this tag" message since October, but new questions using it are still popping up.
EDIT: The tag has since been removed (presumably by the automated job that removes tags which are no longer in use), so I'll be keeping an eye on it to see if it comes back on unit testing questions as unittesting. If it does, then I'd suggest this is ample evidence that it deserves a space on the blacklist.
FURTHER EDIT 15/12/11: The tag has not yet come back from the dead - hurrah! - possibly because typing "unit" into the tag field in the ask-a-question page now results in unit-testing appearing as the first result. Perhaps a blacklist of the unit tag is not required: merely purging it seems to have been effective. I'll keep an eye on it for a bit longer...
FURTHER EDIT 22/12/11 The tag still hasn't reappeared! Time to answer my own question in the negative. And also title to "Should we blacklist..."
