I've noticed that some recent questions have been tagged with both op-amp and operational-amplifier (e.g. this question). The former seems to be the main tag (it has a tag wiki and over 4 thousand questions) whereas the latter has no tag wiki and only 111 questions.
There is no need to have two tags for op amps. I suggest we make these two tags either tag synonyms and/or merge them. Assuming the community agrees, which should be the master tag?
