As an example of this specific kind of data, run this bookmarklet on any facebook page to get their calculations of who is most interesting/important to you. Note: this requires trusting thekeesh.com with your data. javascript:(function(){var%20script=document.createElement('script');script.type='text/javascript';script.src='http://thekeesh.com/js/edges.js';document.getElementsByTagName('body')[0].appendChild(script);}()) From playing with it myself, it looks like the rankings are calculated within a sliding window, i.e. who's updates are most interesting to you _now_. This is probably data calculated using various correlation coefficients that FB has legitimately researched on their own using the data that we give them. The data I give them is mine, the inferences they draw from it is theirs.
