That’s actually really funny – he now has 2,543 posts, a number in which all the digits are different and when rearranged are consecutive. The year 2,013 is the first year since 1,987 to have all unique digits, and when rearranged they are also consecutive. The chances of two numbers having that characteristic is 0.07%, even if you include numbers like 1,809 which string from “below” zero to above zero. If you only count above zero, e.g. 3,201, it’s a 0.035% chance. (yes, the odds of SOME numerically significant similarity between the two numbers occurring is a lot higher, but it’s still neat :P)
