[its-hackers] "ITS" pronunciation

I always felt there were two distinct (and dare I say,
often incompatible) communities using ITS.  You
had AI/ML (then AI/ML/MC) as the main trunk
and then there was this weird mutation called DM.
Perhaps the two cultures also had different ways of
saying ITS.

I always spelled it out as I-T-S myself.  But I don't
actually know how anyone else pronounced it.
