Dave Winer: you're right (as usual)
Social Graph = Social Network
"social network" is simpler / less confusing than "social graph", and it's been around longer too. Mark Zuckerberg didn't invent social networking... however, he did produce the best form of it that's used by millions of people. so i think he gets a little credit.
but while we're at the revisionist history...
RSS = XML
and while you might debate whether XML is simpler / less confusing to say than RSS, and that RSS is a more specific implementation standard, XML was around for YEARS before RSS was proposed.
so if you'll stop calling it RSS, i'll stop calling it the Social Graph.
