The Social Graph is Neither
rdf technology is coming on strong in late 2011;  the tools are getting better fast -- we will be able to represent the social graph in more detail,  and correlate it with the 'semantic graph' that shared human experience is coded in.<p>yes,  RDF has taken a while to mature,  but look at the time lag between Codd's paper and the commercial release of Oracle. 1000 flowers have been blooming for years and we know a lot about what works and what doesn't.<p>the trouble with foaf and other 'distributed social graph' is that muggles like Facebook the way it is...  they don't care about data portability or privacy;  unless a distributed system can provide a better user experience,  it's got no hope.
