Yahoo seems to be doing some interesting stuff with Bluetooth tracking and MyBlogLog. They’re using a java applet to poll which bluetooth devices are nearby, and figuring out who you encounter often. I think there was a study done using this kind of technique earlier, but I can’t remember who did it.

In this context, privacy is obviously a concern. But at least the people installing the software are aware that they’re being tracked. Or do they? Dun dun dunnnnn!
