Where is Azimuth = 0?

Dear SeeSat-members.
When an observer describes his(or her) observation often it is
described by specifying Azimuth and Altitude. I noticed that
many people use Azimuth = 0 being North. I changed several
times in using Azimuth = 0 being either North or South
following a recomendation of people from which I expect they
should know. If I should report a location at the sky I prefer
to use Right Ascension and declination. But I do understand
the coordinates with respect to the local horizon better
describe possible brightness changes. If I should report in
AltAz (Altitude and Azimuth) I normally add S=0 or N=0.
