That's a good rule if you do most of your LJ at home. In my case, most of it is done at work, and I would be sacrificing looking at the dozens / hundreds who do warn to the 3-4 that don't. I would be changing my behavior substantially - and as my f-list scrolls many times over the day it would most likely result in missed entertainment / information.

Not a bad idea, but it doesn't work for my circumstances and preferences.
