Facebook first announced Connections a few weeks ago, and EFF quickly wrote at length about the problems they created. Basically, Facebook has transformed substantial personal information — including your hometown, education, work history, interests, and activities — into "Connections." This allows far more people than ever before to see this information, regardless of whether you want them to.
Lots of confusion about FB's new changes. Not a lot of clarity in the analysis i've read. This is pretty good.
