Well, many people on this board have no idea who some of these hollywood icons are. I mean, Ernest Borgnine was 95. I have no clue who he was. Infact, i just looked him up on wiki, and he won an oscar in 1955, that's even before my MOM was born. It's not that i didn't notice, i just don't really know him.
It's also when people die at an old age of natural causes, it's not really 'gossip worthy.' This is a forum which is meant to exchange gossip, etc. It doesn't mean people care less, it's just, what is there for people to talk about? All you can really say is RIP, KWIM? Death is always sad but in the media, certain news stories attract more attention than others.
