Sure.  I'm curious: in your work, do you use try/catch blocks in place
of 
testing DOM functionality as you go?  E.g.:

         if (document.getElementById) oDiv =
document.getElementById("myDiv")

I don't use try/catch a whole lot because I feel more in control if I
test 
each step as I go along, but I'd be very interested to hear testimonials

praising its virtues or cursing its foibles.

What I generally do, time permitting, is debug on a step-by-step process
as I'm trying to get the script to work. Once I'm done, and the format
is tied down, I compact all the references that "should always be there"
and wrap it in a try/catch block.
