Steam does this themselves by incentivizing votes with badges and profile exp, the latter of which is needed to increase your maximum amount of Steam friends. People vote for the rewards, and as such, so many people vote that you end up "rewarding the good games that everyone played rather than the masterpieces played by only a few." like the article said.

Does this mean we'll be seeing more of the Boneyard and classic lore? Also never seen a vault-boy with the numbers on the chest before, neat.

I'm glad that there's a version of the game without DRM now.
