I got thinking, and the electrical tag is pretty dumb. What's everyone think about nuking, banning, and retagging the affected questions? There are 197 at the moment, 30 of which are single tag.
I was. I also blacklisted the tag. Please look over untagged questions to provide correct tags or vote to delete.
I'm in favor of removing it. While one could argue that we do allow non-electrical questions (signal/control theory, embedded programming, HDL, history...), all of those subjects are on-topic because of their relation to electricity and electrical engineering. Also, there are far more electrical questions than any other kind. Looking at the front page right now, I see one programming question, one control theory question, one pure digital question, and 47 "electrical" questions. A tag that applies to ~95% of our questions does not seem very useful.
I've looked at this on and off over the past week. Now, I count approximately 10 questions with the single [electrical] tag, and some of these questions are very poor - they should be easy to deal with.
I think the tag is safe to remove. The untagged remainder can be cleaned up pretty quickly.
