In my mind, 0 is not a number, as, a number is a representation of a quantity and "nothing" is not a quantity.
I'm intrigued. Can you elaborate on that? In what sense is zero not a quantity?
Related question: would you consider the empty set a set? And if so: would you say that it makes sense to talk about the cardinality of a set, i.e. the number of its elements? And what would the cardinality of the empty set be?
Ever hear the trick statement, i know the score before a baseball game starts? It is 0 to 0.
I think it'd be more accurate to say that it's NULL to NULL, to borrow a term from databases -- though NULL is itself a rather overloaded concept that represents (and, arguably, conflates) many distinct concepts at once.
Hence, the poll question is really, what is the first representational digit in base 1, colloquially asked as "what is the first number after 0".
In that case, I'm tempted to answer "an ε that's smaller than any real number>0", but I'll leave that to people who actually know a bit about non-standard analysis (I don't!). ;)
