The other day, while I was in the shower, it occurred to me that the most commonly referenced date last year was the same as the most commonly referenced date this year. This year you can't turn around without hearing the phrase "September 11." I doubt this was true here in the US, but in Australia last year I was constantly hearing about "S11." It was the name of an anti-globalization protest scheduled for the World Economic Forum meeting in Melbourne on September 11-13. There were S11 stickers all over uni, and it was constantly in the news.

Obviously it's just coincidence that these things happened a year apart, but it's still weird to think about.
