The Internet Is One Big Social Network ( Web 5.0 )

I wonder if many guys take the internet itself like a social network ( faceboob, myspace, hi5, linkedin ). What these websites offer is what the internet also offers but it just needs some components to crown it up to become one. And I guess thats what Google is trying to do with "Friends Connect" and Facebook and Myspace too are trying to expand in the direction too.
 But I think in the nearest future things like myblogLog(www.mybloglog.com) and blogcatalog ( www.blogcatalog.com) are trying to make some social networking out of the internet. I have a nice write up about it here http://mambenanje(dot)blogspot(dot)com/2008/05/internet-is-one-big-social-network-web.html

 I would like to know what African webmasters think about this rapid changes in the online ecosystem.
