Yes, of course Facebook is a great implementation of Social Networking which is undoubtedly the paradigm that will dominate the internet world for at least a few years.  However Facebook is hardly a *new* idea  and it’s hardly immune to other social networking forces that are in the mix now and will be popping up as time moves on.

AllFacebook is reporting that soon Facebook could kill off LinkedIn with new ways to segregate and work with your contact list, and I think he’s got a good point.   Ideally it seems like would be nice to have ONE intersection point that can be adjusted and manipulated according to our network, community, or audience.   But it’s not clear people will want that to be a commercial enterprise – in fact OpenID in some form seems more likely to take on that role. 

Despite all the hype surrounding a 10 billion valuation for Facebook and rumors of their takeover of the world I’m skeptical they’ll be as dominant as many seem to think after a few years of hassling with the real world of real people – potentially very fickle facebookers. 

Facebook is seeking the mantle of the one stop social networking shop, and as of the latest buzz they seem in a good position to take over from Myspace as the world’s top social network.   However Facebook has a very long way to go in terms of subscribers even though it does seem that the earlier enthusiasm folks showed for Myspace is  giving way to Facebook.    But Facebook is not as “fun” as Myspace so I’d guess we’ll see a demographic division as kids and new users gravitate to the more “fun” sites like MySpace or the new Yahoo Mash and more sophisticated users move in the direction of Facebook.
