I make sure to list any weights and measures in both US and metric.
I also try to include a fair amount of content focused on other parts of the world.
Lemmy is small enough that even though I’m guessing it is majority US, that it is likely less US-centric than most social media. It’s just good to have some stuff for everyone, and I know I like to learn about things outside my country, so I want non-US focused content myself on a regular basis.
