Occasionally I notice a topic that has been discussed often enough to merit a tag, but there isn't one. For example, today on Raspberry Pi, a question popped into the active queue about using the DietPi operating system. I've seen these often enough and so went to add the 'dietpi' (or 'diet-pi', or what have you) tag only to notice it did not exist. So I created it by adding it to the question.
Not surprisingly, a site search for is:question dietpi
turned up a list of 50 Q&As. Possibly a couple of these don't merit it, but chances are most of them do, and I'd rather go through that list and remove the ones that look inappropriate than go through it and add them all one at a time.
I know SE has an HTTP and/or JavaScript API that can be used for automating things, but (a little shamefully) I've never looked at it or anything that uses it. Is anyone aware of a script, etc., that could do this? If not, does the API have potential to do so and where could I find the documentation that would help me to do so? All apologies for being too lazy to start digging myself on the last point as I am hoping the script already exists.
