I've been reading the facebook thread with interest. I don't think the issue is privacy, but with presentation. There is definitely a "stalker" vibe to how the feeds read. As far as I can tell, though, it is possible to delete items from your own feed. So someone could easily delete everything if they want no news in their feed, or be selective about it. People have long made mistakes in negotiating issues of self-presentation in their lives, and social networking software simply documents those mistakes. Which rightly makes students more nervous, since many of them are still working it out. We're debating this like it's all crystal clear to everyone what should be public and what should be private, or that the distinction itself is a hard social reality just because it's how the law deals with issues of personal information. It's certainly NOT clear to students, it's not even that clear to facebook's designers, and I'd also submit that in most of our lives -- in actual practice as opposed to legal definition -- there's a huge grey area where most personal information lives. Not totally private, and not fully "public domain" either. --J
