X has a massive user base of over 600 million people from all over the world, which has made it a solid platform for not just keeping up with domestic topics but those impacting other countries as well. It's a common experience for X users to connect with, and even become friends with, users in other countries, though this also means that you're more likely to be exposed to opinions and cultures that may clash with your own. Bluesky, on the other hand, is much smaller with just over 28 million users. Over 40 percent of Bluesky users are based in the USA and most tend to lean politically to the left which may appeal to you if you prefer a place to connect with like-minded people.
