Facebook is now testing the use of its virtual currency, Facebook Credits, on third party sites outside of Facebook. This is a huge move but not an unexpected one: When I wrote an analysis paper on Credits back in May, this was among the top forecasts. Since then, I'd roughly estimate about 25-40 million people regularly using Facebook Credits now, just to play games within Facebook. Since then, there's also a lot of non-gaming content you can buy with Facebook Credits, such as music and TV shows, making this install base much more likely to grow. And if this trial launch of third party sites is successful (as is very likely), I bet we'll see more content being offered for Facebook Credits, even physical products and services. That's right: Facebook Credits are on track to become the Internet's official virtual currency.
Speaking of which: Hey, Linden Lab, I hope you're applying to become a third party site that sells your own Second Life virtual currency for Facebook Credits. I really think the nearly 200,000 people in your Facebook group will be excited by that offer. As will the hundreds of thousands more who would be, after it went online.
