Wait, all of this "not really a number" and "carry-over from binary" stuff deals with the *numeral* zero, which is neither here nor there. We could use a picture of a bunny-rabbit instead of the numeral zero, making this year 2<bunny><bunny>6.
The discussion here is over the *value* zero -- the identity element under addition, and the number A such that A * X = A for all X. It's the first of those properties that makes it important in computer programming, and in more general terms considering the null (i.e., zero) case is always important in programming.
