As a rule, you'd best avoid peering behind the scenes of your favorite online pastime; you probably won't like what you find. Drill into the backstory of "Mafia Wars" creator Zynga, for example, and you'll find a sweatshop where ruthless managers closely monitor the performance of even cafeteria workers, and where employees are pitted against one another and bullied into emotional breakdowns.

Emma Stone has had three movies come out in as many weeks, so naturally she's been on just about every talk show imaginable recently. You'd think she's run out of interesting anecdotes by now, but Stone's interview with Jimmy Fallon on tonight's Late Night was actually kind of adorable. Watch Stone discuss her paranoid fear of Twitter and the FarmVille addiction that forced her to delete her Facebook account in the clip above.

If there is one takeaway from Vanity Fair's long profile of sordid FarmVille pimp Mark Pincus, it's that obnoxiously flaunting your funding and coarser instincts like a blowhard is threatening to come back into fashion, just like in 2000.

Hey! Looks like exploiting the weaknesses of addicts and kids does pay off: Investors are considering pouring another $250 million into gaming company Zynga, Inc. "in a deal that could value the three-year-old start-up at between $7 billion and $9 billion," according to The Wall Street Journal. That's right, the company behind Farmville is worth—according to always-rational investors—seven billion dollars. Time to short the human race. [WSJ]

Bill Hader's impression of the founder of WikiLeaks appeared again on SNL with a list of sites he'll mess with until he's out of jail. The list will affect us all: Amazon, Orbitz, Facebook, Farmville, and the beloved Netflix queue.

Zynga, the more-than-a-little-sketchy company behind the insanely popular Facebook game Farmville, is debuting a new product: Cityville, "Zynga's most social game ever." Great! Because what Facebook really needs is another blockbuster game that constantly encourages people to invite their friends.

Florida mother Alexandra Tobias has pleaded guilty to killing her infant son after shaking him for crying while she was playing FarmVille on Facebook. She shook him, "smoked a cigarette to compose herself," and then shook him again. Yeesh.

According to a new report in The Wall Street Journal, nearly all of the most popular apps on Facebook—including Farmville, Causes, and Quiz Planet—have been sharing users' information with advertising and tracking companies. Here's how to stop them.

The company behind Mafia Wars and Farmville doesn't like to talk about the sad addicts who fuel its profits. But it does quietly run a special store for them, where imaginary credits are bought with very real bank transfers.

A British kid stole his mom's credit card and blew more than £900 on FarmVille, the Facebook game infamous for its seedy advertisers. And amazingly the shameless company that runs the game won't issue a refund.

Last night's South Park illustrated the growing problem of Farmville addiction. Apparently, full-fledged breakdown can be reached with only three days of your farm's growth stagnating. Thankfully, Stan fertilizes Kyle's farm and everything ends well.

Tonight, South Park made comment on Facebook and its obsessives by brilliantly taking every ridiculous thing about what the social network has become and explaining it with hilariously awkward (and eerily accurate) "IRL" interactions. Inside, the best—and funniest—moments.

Health insurance industry trade groups opposed to President Obama's health care reform bill are paying Facebook users fake money — called "virtual currency" — to send letters to Congress protesting the bill.
