Youtube - Rank vs. Like?

Since I think Lost has about 5 million too-many characters, I'm going to ask our vast audience which method of rating YouTube videos they prefer - the old-school 5-star rating system, or the new-school like/dislike rating system:

I'm personally a fan of the star-system. While 5 isn't too much higher than 2, and overall, I'd imagine the average rating for a video is very similar between the two methods, I would at least enjoy the opportunity to think my nuanced 4-star rating makes a difference. Call me old-fashioned or adverse to change, but I don't think I'll be changing my mind anytime soon.

Ambidexterity - WTF?

Apparently, the ability to be ambidextrous is something that can be learned. Who knew? I tried to brush my teeth left-handed last night; it didn't work, and that was with an electric toothbrush purchased through the randomly awesome site known as Woot (yes, I linked to Woot for no apparent reason; live with it).

So, I ask you - is there any task out there in which you'd consider yourself ambidextrous?
