The 7 Best Jobs for Facebook Addicts

Tech reporter/blogger: It's your job to scout the Web for stories and build a big pile of sources for tech-related scoops. Sure, there are Digg meetups to attend, but tech reporters and bloggers belong online. Look at TechCrunch founder Michael Arrington, who has turned his site into the source for Silicon Valley news. Aside from his site, Arrington has friends on Facebook, gets the news out in bits on Twitter, and makes connections and shares his résumé on LinkedIn. However Arrington gets his scoops, he's clearly not hard to find.

Lacy says she likes to use her Twitter account to cull ideas and sources for her BusinessWeek.com columns. At different points in her career, she has found Facebook or LinkedIn more helpful—"I think it just depends on what you're trying to accomplish at that period in time," she says.

Product managers and developers: Product managers keep their eye on consumers. They're looking for what drives their decision making and then translating the consumers' wants to developers, who build that into the product, Epstein says.

"These companies, like Facebook and all their competitors in the social networking world, they want their engineers and product managers to be avid Web 2.0 users themselves," Epstein says. "So they know themselves what they would want in an application, in a feature, so that they then could develop it, basically."

While a developer usually has a computer science degree or even an electrical engineering degree, an ideal product manager knows technically what it takes to build a product, plus has a strong dose of business acumen, according to Epstein. Many product managers start out as engineers and transition into the business side, sometimes picking up M.B.A.'s on the way.
