Does tagging a question error really add much information to it?
Or should we dispose the error tag?
I have blacklisted error.
That seems to be the very definition of a meta tag.
No one is going to be an expert in all errors.
No one is going to follow that tag.
It cannot, by itself, describe the question.
Most damning of all, it is useless without some other tag to say what app there is an error.
I say it should be burninated.
