For me too. It's both cultural and generational, I guess. It's pretty hard to find references that are widely understood. One usually writes from one's own frame of reference; knowing what others know isn't easy. Just like I don't know the names of Saturday Night Live hosts (something that slowed me down in an NYT puzzle recently), a puzzle maker in New York has a hard time imagining the things I do know about (in this case) US culture.

Across ages might be a bit easier, because there's more material at hand in your own language, but I do notice a considerable distance between me and my daughter in all kinds of knowledge. E.g., I haven't keep up with pop since ages.

But it's a nice, and nerdy, game format.
