@Vierkantor The thing is, Wikipedia says a lot of people leave the initial zero and start directly with one. And I've seen it else fairly often too, because I prefer 0, 1 too.
@Pixdigit
I never saw it starting with 0, so I did some research:

Comparably with 0 being a natural number or not (ordinal vs. cardinal view).
@Vierkantor
@Pixdigit the 0th element of the sequence is 0, the 1st element of the sequence is 1
