Guys, let's not confuse ourselves here. I'm fine with the prefixes, but only as long as they're not mandatory. And I'm a absolutely against eventually switching the meaning of Bitcoin and BTC to represent micro-Bitcoins. This is a horrible idea. Just think of what the final number of BTC will then be: 21 trillion. Not one person can wrap his mind around it, and it is a prime reason folks hate global economics. It's all the meaningless trillions floating around.

Also: don't forget the "small calorie/large calorie" travesty. Everyone's still confused to this day. cal? Cal? kcal?
