By the word social (and now I think it can mean different things in different context), I meant that it is based on the concept that there is content which is common to a given 'social' group -- let's say with your friends who use Linux, you can use it to download a 10 GB distro. The set of those friends forms a social group that will participate in downloading the distro. You are right about the 'geo-aware' part but then there is no geo-awareness; it's all manual.
