When I returned to Steem in July last year, I found that country tags were a must for contest entrants in some communities, and by country, it means the author's home country. Since then I have always written the country tag as one of the first 5 tags of each of my articles.

Also, I think the country tag was once an important tag for curators working by country, or perhaps at a time when Steemit Inc had CRs (Country Reps) before CRs were cancelled and Steemit Inc. introduced SRs (which as the name suggests, are supposed to work regardless of geography).

In case I visit another country or write something related to another country, I will use two country tags, readers will understand the reason. I don't think there is any restriction on that, even in certain cases, more than two country tags are also possible, as long as the content of the article reflects that, even though it might seem like something that ‘doesn't make sense’. I have done this in the book review article Musashi (Novel by Eiji Yoshikawa) - More Than Just A Martial Art Novel (the book was written by a Japanese and the article happened to have a huge proportion of Japanese tradition talk, especially related to martial art.) and the film review The Quiet Maid (Calladita) [2023]: The First European Feature Fiction Film Ever That Was Funded with NFTs! (And It's A Good Watch) (a movie made by Spanish filmmakers).
