I noticed there is an electronics tag that seems a bit redundant to me. It appears to be used on a lot of questions migrated from Physics.SE such as Resistor on anode or cathode? presumably because it's one of the few common one between sites, but if removed those questions would be migrated as untagged as is the case with An amplifier with feedback.
There are 75 questions tagged with it at the moment and most look like they could do with better tags being applied rather than it being burninated. I wondered if there's any objections to it being removed gradually via edits and maybe an edit on the wiki for the tag to say it's deprecated?
