This avoids the following:
Including multiple newsgroups in the posting of a single post--causes any
reply to that post to be sent to ALL the newsgroups that single post has
been posted to...

Which is basically what you want ... all the newsgroups being involved in
the conversation. When you cross post, most newsreaders can recognize that
and mark the posting already read in the other newsgroup. While not
everyone may be subscribed to all the newsgroups, a lot of people will if
they are related subjects. This avoids them reading the same post multiple
times. It also avoids duplicate responses. If you multiply post and get a
valid response in a newsgroup I don't read, I may well repeat essentially
the same response.

If it is appropriate to cross-post (and it is often overused), then it seems
far better than multiply posting essentially the same message to different
groups.
