I bring your attention to the tag how-to
...what the holy batman is that? It's a meta tag. It describes nothing about the question at all, doesn't help categorize the question, help anyone find the question. It doesn't do anything.
I see it was added a long time ago exactly to be a meta tag, but looking at the questions in the tag, I don't see how it helps anything.
It's no better than having a question tag if you ask me...
Can we kill it?
