Thanks, this gets me a little farther along.  

When we say "send a trackback ping"...  is this something that the 
blog software does automatically (when an article is posted,
scan it for links to external sites and automatically ping them),
or is it something that is manually initiated by a person...? 

Also, does this mean that each page/article needs to be keeping
track of any trackback pings it has received?  If so, then what's
the standard mechanism for dealing with spammers who might
use trackback pings to create lots of links to other sites...?
