I'll add, probably much to Shal's dismay, that the trend toward "automating
everything" just results in more and more and more having to be automated
because users are never taught how to do simple things themselves.
If there exist, and I do not doubt that there do, interfaces that do not
allow trimming of quoted content the solution to that is to ask for an interface
change.
For myself, and many others, we want to select what we wish to keep or remove
and not have software second guess that for us.? I have, on occasion, had
quoted material 4 and 5 levels deep, though generally short segments, because it
was necessary, in my opinion, to keep it for context and continuity.
I actually do not get, at any level, the resistance to trying to teach
netiquette seems to get from many quarters these days.? Every context where
written communication is the norm has conventions, and e-mail lists and online
forums are no different.? There really are things that an individual should
be expected to know and consider and, if they don't, be advised - nicely and
delicately at the outset - that they need to do so.? It's really not too
much to ask, it's the minimum that should be expected after a very short period
of time - read: weeks at most - in the online forum/e-mail list world when it
comes to common points of nettiquette.
