These tags are mostly accidentally created and should be removed.
These should be removed (maybe even blocked if there is an option in the SE engine) because they are too vague.

Synonyms require significant reputation or moderator abilities to create. The "master tag" (or whatever the proper term is) will replace the synonym when typed.
- atmega328 I don't know what to do about this one really but often people tag this along with uno/arduino-uno

Tags to watch in the future...
Tags for topics that may be deemed off-topic soon.
- enclosure Will we allow shopping questions here?
