Some may be off topic, but in general I think it's as good a place to find videos as anything else. I tend to bookmark 1-3 a week, if it is tagged +someday or +todo then all bets are off on quality, as it means I saw it referenced somewhere or tweeted and bookmarked it for future reference.
Also, if you want you can see all the ones I've bookmarked on my delicious account:
