Sure, but in practice -- for 95% of the people on my flist, myself included -- every week hasn't been blog against racism week. So I figure it's more useful as a kick in the pants/an excuse to start than it is limiting; there's not much out there to limit.

And urgh, laptop batteries. My battery's been at about 1.5 hours for years. Somebody told me once that the more you leave your computer plugged in when it's already fully charged, the worse the battery gets. I hope she was wrong.
