I'm not a Gentoo user myself, but I feel compelled to mention another way in which Gentoo has made a difference and continues to make a big difference.
The wiki.
The Gentoo wiki contains gems of information on all sorts of under-documented parts of the infrastructure supporting modern Linux. While things like udev and hal are documented, it's in a very limited "useful if you already know what you're looking for" style. The Gentoo wiki, on the other hand, seems to constantly turn up in searches for information about actual issues or tasks.
The people contributing to the Gentoo wiki are doing great work, and it benefits all Linux users not just Gentoo users.

The official Gentoo stance wrt Gentoo-Wiki.com isn't quite as glowing, and is best summed up by this post:
"Gentoo-wiki does not now nor will it ever get linked to from official
Gentoo media, documentation, or anything else within the www.gentoo.org
namespace...
It is inherently unreliable and outside of Gentoo's control."
If Gentoo-wiki was Wikipedia

"Wikipedia does not now nor will it ever get linked to from the real internet, or anything else within the .com, .org or .net namespace... It is inherently unreliable and outside of control."
...and yet; on balance, really quite-a-useful repository of heavily linked-to information!
