Who is more important to gaming, Mark Zuckerberg or Bill Gates?

Mark Zuckerberg and Bill Gates both are important to gaming.
In my opinion, Mark Zuckerberg is more important to gaming. Because Zuckerberg is standing on the shoulders of giants. Zuckerberg announced Facebook Platform on May 24, 2007. Facebook Platform is a development platform for programmers to create social application within Facebook. Facebook platform is a new platform in gaming. According to the statistics, as of January of 2011, there are more than 600 million active users on Facebook. Moreover, the applications ssuch as FarmVille and CityVille are very popular online games besed on facebook today. They are probably the future canon games.

I think Mark Zuckerberg is more potential and innocative to gaming in the future.
