Tag cleanup TLDR: Let's get rid of the current tag.
Following up with this question on broad overused tags, I would like to see how people feel about cleaning up some of the really useless tags that we have, such as current, voltage, power, and circuit. Generally speaking, one tag should not apply to the vast majority of questions on this site otherwise it doesn't add any organizing value. I would like to go through each of these four tags and figure out a long-term strategy for managing these tags.
The current tag:
Currently (ha!) there are 512 questions that are tagged current. Of those 512, only 19 are only tagged current, the rest have other tags. This means that there are relatively few questions that must be retagged in any case. This means that if we just nuked the tag, the untagged results would be easy to deal with.
What do we do without a current tag!?!?
There are a few different use cases for the current tag:
- It's used just to add another tag to the question
- circuit-analysis (Covers most of the homework and class problem questions)
- current-source and current-sink
Let's nuke the current tag (administratively delete it from all questions in a way that does not impact the front page), and blacklist it so that it doesn't come back. Future questions will not be able to use it, and we will need to retag 19 or so questions, which will not put a huge load on the front page.
Ideally, all the questions tagged current would be manually retagged. At 500+ tagged questions, this would take a long time and pollute the front page with minor edits. Additionally, new questions will be added that misuse the tag. It is possible to blacklist a tag so it can't be used on new questions, but it will cause edits to existing questions with the tag to fail (apparently in a way that will cause a lot of confusion). Nuking the tag (administratively removing the tag from all questions that use it) is probably the most realistic option for big tags, but we are basically deleting information about those questions.
