Henry Ford. Creative force behind the automobile, altering American industry and transportation and allowing us to get the heck away from each other.

Mark Zuckerburg. Creative force behind social networking, altering American industry and communication and allowing us to get the heck closer to each other in ways that we never believed possible (Facebook does a better job at making me hate people and things that I thought I only might hate; it rarely works the other way around, though, bizarrely.)

These men are on opposing sides of the entrepreneurial spectrum, with Ford embracing solitude and Zuckerburg loving being all up in everyone’s junk. But an interesting tidbit of news brings both together in front of Facebook’s IPO on Friday. (Or at least the industry Ford helped create.)

General Motors is the third largest advertiser in the country, behind Proctor and Gamble and AT&T, so it’s a pretty big deal that GM has decided to pull its paid advertising from Facebook. The automaker has been unable to determine the effectiveness of the ads (GM spends $10 million of its $40 million Facebook budget on advertisements), and will instead focus on the content it uploads to its company pages on the social networking behemoth.

This is not the best news for Zuckerburg, as Facebook is trying to raise billions in Friday’s public offering. When a pillar of American business begins questioning the viability of handing money to Facebook for its advertisements, investors have to wonder just exactly how Zuckerberg will monetize the website and all that data they get from us.

Ah, the weird intersections of American zeal, capitalism and digital technology.
