Here's our stock answer:
It doesn't matter.
We said nineteen-eighty and no one thought twice about it, though we probably should have thought twice about the shoulder pads and auto-tinting glasses. So twenty-ten is just fine. We also said "The Year 2000" (insert ominous sound effects), so calling it two-thousand ten isn't going to confuse anyone. And that's really the point of thinking about language and what we call things. Is our meaning clear? Then huzzah!
Anyone who does get in a kerfluffle over this could probably use a hobby. Still, the debate is better than the one about whether 2000 or 2001 was the first year of the millennium.
And now, we'd like to toss the issue to the fray. Is there something we're missing? Why do people care about this? Is there some point of clarity, elegance, wit, and/or style that can be achieved by sticking with one over the other? Do tell.
*Note...Blogger isn't letting SPOGG post comments today, but we wanted to respond to the "kerfluffle" kerfuffle in the comments. The word appears both ways in various dictionaries. According to the OED, it was originally "kafuffle" and has appeared as "kuffufle." We like to think of it as the sound effect made by scuffling feet in a fight. The spelling depends on the shoes you're wearing.
