mantis2009 writes "Paul Adams, a senior user experience researcher at Google, has posted a slideshow from a recent presentation that shows insightful research into how people use social networking technologies. The presentation describes several shortcomings of existing technology, and it highlights specific modalities that current technology (ahem, Facebook) gets wrong. Adams concludes that social networking applications are a 'crude approximation' of real-life social networks. 'People don't have one group of friends,' Adams research in several different countries shows that in reality, most people have between four to six groups of friends. He argues that social networking applications need to be built with that reality in mind."
