This seems very anecdotal. It would be interesting to see some numbers on how different age groups interact with different UI types.

In my experience, most people prefer "card" view type interfaces. Most popular sites I can think of at the top of my head are like this. Instagram shows you a picture. Facebook you default see a post until it is truncated. New Reddit is like this as well. Twitter shows just a small post, and you can view threads that way too.

Even old sites that had list views tended to get more popular when you get a card view, like Reddit.

I'm not sure if it's generational.
