Is Twitter Trying to Map Social Graphs on Twitter?

Twitter was trying to define social graphs based on new archetypes like the new left or rationalists or you know de-gen's or crypto people. If you reached a certain point it showed you where you were on this map and it was really interesting because it was funny I think I tweeted something along lines of 20th century subculture, 21st century sub cluster which is more like kind of clustering of different groups then diagrams that you happen to fall into on a social graph. It took a young developer to query the twitter API to kind of expose that but of course as Holly said that was already kind of attempting to happen in some way.
