It looks like we will soon be able to gather all of our data from Facebook. I can only imagine that this will again increase the amount of data we have to deal with, and will bring up security issues as well. That shouldn't be a huge problem for individuals, who can opt-in/out as they choose, but perhaps for corporations with pages and profiles on Facebook that would be some very good information indeed (data mining anyone?), as they can see who their friends and fans consist of. That kind of information can be very valuable.
Facebook also announced a few more handy features, like design changes and a change in the way groups operate, namely that they will try to facilitate your social circles more rather than be simple constructs to organize people. Check out more at Gizmodo, who has done a good job summarizing.
