In the DIY.SE folksonomy, the electrical specialty's tags stand out as a cross-connected pile of confusion, and one of the chief culprits is circuit.
While not particularly rare (129 questions use it), a quick glance at the first few dozen questions using it reveals only a few that could be routed to an electrical expert by way of circuit -- most of the time, it's used in a redundant fashion with electrical, wiring, or another tag in the electrical specialty.It's gone now.
Should we burninate this tag for how little value it provides? Synonymize it with say wiring and migrate questions using it otherwise off of it? Or leave it alone for now and check back later to see if it's grown as a problem?
