Currently there are tags for usa, uk, and canada.
Are these tags needed, or should this information be noted in the question body instead?
They do seem to be meta tags.
Would the questions be OK if these were the only tags?
Do the questions still make sense if this tag is removed?
If the answers are "no" and "yes" then they can be safely removed.
I am not sure I agree with the accepted answer. I have actually missed this thread and posted a new question, but here are my arguments in favour of regional tags in context of this thread:
So I see a critical difference between the regional/locality tags and the so-called meta-tags, and would like to re-propose introducing them. Please read the related question too, to see examples and answer that one.
For me, the solution would be to require a country/state/province in the profile in order to post a question. But, it's a one-off for DIY, so I doubt it's practical
