I don't like [nice] tags!

Apparently we have a nice tag! So lets evaluate it for burnination!

Does it describe the contents of the questions to which it is applied? and is it unambiguous?

Well, if we look at the description for this tag, it states,

nice is a UNIX kernel call and the name of a utility employed to lower or raise a process' CPU priority.

I'm not a Subject Matter Expert here, but it seems to be a UNIX function or something. And people could obviously insert this tag as a joke, because that's how I found this tag.

Why should we even have a tag for every single UNIX command?

Is the concept described even on-topic for the site?

Well, UNIX is technically on-topic, but maybe the UNIX StackExchange site would do better with this tag, since it is wholly based on UNIX.

Does the tag add any meaningful information to the post?

No, IMHO it does not. If I am using the input function for a program in python, I wouldn't add an input tag, would I? If I was trying to run a program, I wouldn't add a run tag, would I?

Does it mean the same thing in all common contexts?

Well, not really. Sometimes new users create a function in their program called nice and then tag it with this, which has a different meaning from the UNIX command. I could also interpret it as, "My question is nice!". It has many different meanings.

So should we burninate it?
