Sex Differences in Intimate Relationships (PDF) -- Albert-Laszlo Barabasi and others use social graph analysis to analyze communications patterns in relationships. Notice that not only does the preference for an opposite-sex “best friend” kick in significantly earlier for females than for males (~18 years vs mid-20s, respectively), but females maintain a higher plateau value for much longer. More reality mining to understand ourselves. (via Sean Gourley)
Digital Mirror Demo (video) -- demo of the Digital Mirror tool that analyses relationships. Some very cute visualizations of social proximity and presentation of the things you can learn from email, calendar, etc. (via kgreene on Twitter)
Chewie Stats -- sweet chart of blog traffic after something went memetic. Interesting for the different qualities of traffic from each site: As one might expect, Reddit users go straight for the punchline and bail immediately. One might assume the the same behavior from Facebook users, but no, among the visitors that hang around, they rank third! Likewise I would have expected MetaFilter readers to hang around and Boing Boing users to quickly move along; but in fact, the opposite is the case. (via chrissmessina on Twitter)
