T.J., while I absolutely agree with what you have said, I think you're
missing part of BearState's question:
"Some knuckleheads might well be provoked to say, "Hey, I didn't get
my
data. There's a bug." "
The trick then is to make something happen visually to show the user
that something is happening: an animated cursor, an hourglass, even
just temporarily change the colour of something.
Some Scriptaculous facilities provide this for you (see 'indicator' in
http://wiki.github.com/madrobby/scriptaculous/ajax-autocompleter, for
example, but I think you'll have to do it yourself with the basic
Prototype Ajax classes. But it's not hard. You set something in the
'onCreate' callback, and remove or stop it in 'onComplete'.
