There's a bit of strategy involved.
"NPR" is short for "National Public Radio", where "National" means the USA. But the Fediverse is inherently international. How to deal with that?
I notice Fediverse accounts from the USA that rather ignore the ~96% rest of the world's population. Which is a possible, maybe even reasonable choice.
If you choose differently, interacting with us needs thought. Do you want to require your target group to understand phrases like "meeting at 4 ET"?
