True, but the intent of the NATIONAL GENERIC CALLS
is not to communicate traffic, but to post a solicitation
to comunicate.  It is used to announce your station's
call so that others will see your callsign and then be
able to initiate a message back to you.. 

THis is needed because APRS users cannot send
messages outside of the local RF lan, unless the
callsign of a distant station is known.  By posting
a message to the generic calls, then it lets you
get your own callsign out... (or at least now to
a FINDU list).
