Well, call my ornery then.
If you want people to read your message and provide help, then you owe
it to them to figure which group it belongs in more than the others.
I find it extremely rare that a cross-posted message really belonged in
both groups. You may see it otherwise, naturally.
Sure, but note that some people will then ignore the message, or at
least its followups. So one should think about which method will get the
most people to read and rely to a message.
Didn't Jukka Korpela say that any message x-posted to more than 2 groups
is not worth reading? I'm not sure, but he does offer this:
Note that you or others may feel differently about x-posting. I've said
my piece. Let's avoid a long meta discussion if we can.
all the best.
