Are people in your country not using Bluesky?

See if there's a subreddit for your country. Even if it's not very active, you could ask what other social networks they're using.

It seems like the answer would be country dependant. I have found a great group of people on Bluesky, but it was very easy to find people who like a band that I follow. I'm not sure how easy it would be to find people interested in talking about your country, but I think it may be worth checking out if you haven't.
