A lot of people seem to buy into this backjustified belief that if someone can see your friend-ofs list, that's a source of drama and insecurity. Since everyone seems to be arguing for security through obscurity (with a few outliers arguing to outright hide that information in all forms, since they're paranoid information-hoarders in unreasonable ways.)
This isn't meant to be used to actually harass anyone or to invade their privacy, but rather to show you that the information is actually always available, and that further, you shouldn't be information-paranoid about these sorts of things. This information probably can't even be used to harass anyone. Why would it? That's absurd.
The post to suggestions that inspired this. Check out the thread that followed. Lots of cargo cult privacy/security.
