Creating a Better Facebook
Fed up with Facebook's insatiable need to continue to expose your personal information to ever widening circles, four NYU students have decided to build an open source, distributed competitor to the social networking behemoth. They've raised a few grand, but I imagine it will be harder to convince your mom to log in.
Then again, MySpace did have a userbase comparable to Facebook. And yet it seems to have gone from being the the place to be to "are you still on myspace?" in a very short space of time.
If social networks function in the same way as (say) eBay, then you'd be right. In that case the size of the user base is itself a resource that draws in more users. But suppose there's a different dynamic at work. Suppose it functions like a fashion accessory. Then users could prove a lot more fickle that you'd expect.
A lot of the people driving adoption for new networks are kids. Then the parents follow so they can keep an eye on the children. Before long everyone's on the new network, and aside from a few die-hards, no-one wants to be seen dead on the old sites. And then the kids start looking for a place to hang out that their mums don't know about, and a new generation is coming up that doesn't want anything to do with what their big sister thinks is cool...
I could be wrong, of course. But it would explain why none of the previous social networks have managed translate users into longevity.
Don't let THEM immanentize the Eschaton!
