so what is a blogger?

if you have a blog, does that make you a blogger?
if you have a blog, but you dont update it? does it mean you are no longer a blogger? (assuming you were a blogger in the beginning).
if you have a (or several) blogs? can you claim not to be a blogger?

so what makes you a blogger?
conversely,
what doesnt make you a blogger?
