It's still used in a couple of specific senses - it's used in the nearly fixed phrases "keen edge" or "keen mind" as a synonym for "sharp", and as "to be keen to -" to mean "eager". But, in my experience, it's rarely used to mean grieving ("to keen over -"), and almost never as a generic term of approval ("that's real keen").

Brits still use the word somewhat frequently, though I haven’t bumped into many of them in the last ten years.

Keen is definitely a word but when used to describe a person it’s often a bit of a backhanded compliment… you don’t really want to be keen.

Saying "I'm keen to do x" or "he's keen to do y" is a fairly common normal usage but having said that, wouldn't normally be my first choice of language as a millennial, maybe does sound a bit old fashioned

Right, as far as live exposure, I associate its usage with UK/AU/NZ expats in my western US, academic R&D microcosm.

Yeah, I guess I can also see it as more of a Britishism (etc.) currently.

I'm also a native English speaker, sounds perfectly normal & commonplace to me.

“It offers fewer words for the people directly around you, but more for belonging at a distance” - the further I get into this article the more it just seems like sampling bias as a narrative.

It's a wordy (/AI?) way to say it, but I took it to be commenting on our lives being more 'abstract'/digital than they were, so naturally a lot of our language is less physical.

Oughtn't really affect emotive language like 'keen', though.

Still in common use in Britain as far as I know. A more local (Bristolian) word would be "keener" used to describe someone who puts lots of effort into a task to win praise.

In Canada I hear keener more often than keen (although both are rare).

It's used in Australia. "who's keen for some beers?", "keen as", etc
