YOU KNOW, THIS IS GOING TO COST FACEBOOK BUSINESS, I THINK: Facebook’s Zuckerberg now building a political network. ” After largely sitting on the political sidelines for a few years, the 29-year-old Facebook founder is using his clout as a top business executive and American success story to advocate for comprehensive immigration reform. This week, Zuckerberg will publicly dive headfirst into the immigration debate that’s captivated Washington by joining forces with pro-immigration advocates outside of the tech industry.”

UPDATE: David Kirkham emails: “Facebook getting into immigration reform? He didn’t learn anything from the great fall of Oprah?” Oh, yeah. Her. She was big back before she endorsed Obama.
