I'm not sure why, but I always think about this. How will you pronounce 2010, 2011, etc...?
Most of us currently say two-thousand eight (2008), and will likely say two-thousand nine (2009). But will you say two-thousand ten, or say twenty-ten?
I propose twenty-ten. I doubt that people a century ago said one-thousand nine-hundred ten. Fuck that noise, they said nineteen-ten.
Why has this question consumed me for the past 5 years or so?
