Well, since it was pg's idea, I'd guess "hacker" would slant more towards MIT-style hacks than anything to do with the valley.

I think the lack of Vint Cerf stories has more to do with the temporal nature of news than any biases that people might have. I'd chalk it up to him just not making news lately. Any text on the history of the Internet, TCP/IP, and networks in general liberally mentions him.

It's interesting to examine which historical figures have been remembered and which have been forgotten. Money is part of it but not the full story. Political leaders during times of chaos are remembered. Artists are remembered, many of which died penniless. Mass murderers are remembered. I think in general people just need a simple story to attach to a single person to remember them. Building a computer and making a billion dollars is a simple story. Walking on the moon is a simple story. Designing packet switching protocols is not. It's not a tragic situation it's just interesting to note.
