One should avoid posting "recent" events---sports scores, a plane
crash, or whatever people will see on the evening news or read in the
morning paper. By the time the article has propagated across all of
Usenet, the "news" value of the article will have become stale.
(This is one case for the argument that Usenet news is a misnomer.
{Note that the Clarinet News service (Clarinet) offers news items in
a Usenet format as a precise alternative to the morning paper, et.
al.)
