Start by cleaning up the edges
Bad tags are often harbingers of bad questions. So if you're about to remove a bad tag, start by removing the bad questions it collected: find closed questions and delete them, find downvoted questions and close them (if they warrant it), find poorly-written questions and re-write them (if they deserve it). You get the idea.
When a tag is merely ambiguous, sometimes it makes more sense to just replace it with another tag, or one of a number of other tags. This can be a quick way of turning a bad tag into a good one, or at least accomplishing something other than raw destruction when removing it.
This cleanup is easily the hardest, most time-consuming part of the process. Document your progress here on meta, so that others can see what you're up to and get involved - many hands make light work! And again, if you don't think it's worth doing then just drop it and move on to something else.
There are several tags that there's clear consensus should be removed, but there's no indication that someone's done this cleanup work. To be clear, the tags that need this check are:
- All gone!
For each of these (excepting maybe death), make a post here documenting the work done to check that it's okay to remove the tag completely. Once each has been checked, we'll have the tag removed.
These tags are gone now:
