Thanks for the link; it's a good one. I don't actively avoid information, but I'm still happy when I discover that I don't know a celebrity fact.

There's a balance. You shouldn't let yourself be made to feel awful about not knowing which celebrity is supposedly sleeping with who, etc, to the point where you move a lot of time away from learning other things toward learning that. Pride in your priorities would help to avoid that. At the same time, I certainly agree that getting carried away and purposely avoiding such knowledge is unlikely to be helpful - and some of us no doubt need to temper the tendency.
