Two thousand ten or Twenty Ten?

This argument is a bit ridiculous to me. Why is anyone debating? Everything is getting smaller and smaller--faster and faster. With the number of times that 2010 will be printed and spoken, it only makes sense to pronounce it Twenty Ten. This will allow for more concise vocal broadcasting of any kind. Think about it, a few years back, it became proper to use one space after periods in academic writing instead of two; why? To save a little space on each sentence, on every article, multiplied by millions. Why would this be any different?
