From O’Reilley Radar: "there are nearly 5000 Facebook applications, and the top applications have tens of millions of installs and millions of active users. The bad news, alas, is in our report: 87% of the usage goes to only 84 applications! Only 45 applications have more than 100,000 active users."
From Content Matters: "one of the obstacles to using Facebook for business purposes is that there’s only one class of friend. If I wish to link to another Facebook user, I become their Friend. There’s no way to differentiate between whether it’s a personal friend, a co-worker, a client or a partner."
From The Long Tail: .."Right now the world is focused on stand-alone social networking sites, especially Facebook and MySpace, and the fad of the moment is to take brands and services there, as companies build Facebook apps and MySpace pages in a bid to follow the audience wherever they happen to be. But at the same time there’s a growing sense that elements of social networking is something all good sites should have, not just dedicated social networks. And that suggests a very different strategy–social networking as a feature, not a destination." ……….I think about the current Facebook craze and the notion of it as an all-encompassing platform, sucking in functionality from other sites across the board, I find myself skeptical. With my Long Tail hat on, I think that one-size-fits-all will fail in social networking, just as it has everywhere else. ….Instead, I think focused sites that serve niche communities will extract the best lessons from Facebook and MySpace and offer better social networking tools to the communities they already have. I’m sure huge and generic social networking destinations will continue to do well, but I’m placing my bet on the biggest impact coming when social networking becomes a standard feature on all good sites, bringing community to the granular level where it always works best."
