Someone posted this workplace.SE meta post in chat earlier, and I think this idea is just so good for Travel.SE.
The idea basically is about adding country flags to the country tags, something like:
How can we implement that here?
The problem that WSE has - people ignoring country tags - isn't particuarly a problem here. In general, in fact, I don't think adding little flags solves any problems we have.
But it looks nice, and can only boost clarity. If it's possible I think we should go for it.
Bonus Q: Do we also do this for "citizens" tags?
I agree with the flags in country tags and I would also like them in 'citizen of ... country' tags.
I use other sites, and in some of them flag are or have been used. In case of Yahoo Answers 'have been' and my friends there and I have not been happy to see them disappear.
It did not solve all 'wrong country for the answer' problems but that was mostly because they were added based on the log-in country rather than based on the text as we do here.
I am going to echo Monica's answer on Workplace and say that I'd rather have a generic and neutral icon like a globe next to the country name, rather than a flag:
While arbitrary icons would cause confusion for people who've seen this on SO, thinking our icons are corporate sponsors too, I think a single, unambiguous icon -- such as a globe -- that's used on all the location tags would avoid that problem. An earlier version of this answer proposed using flags (so the tags would have different icons), but, on reflection, a single icon that signals "hey, there's a location tag here (so pay attention to it)" would be sufficient. I hope it would also be easier to manage.
