Some of it client side data validation that was done a long time ago 
before frameworks made server side data validation less of a PITA. 
Some of it is to enforce rules the users asked for ( example, if check 
box A is selected client side, disable textfield B, etc, etc ).  Some of 
it is AJAX used to decrease the number of screens the user has to 
submit.  Some of is gluing in various JQuery features, like a pop-up 
calendar for picking dates ( not something I asked for, the users love it ).

Awesome, thank you.

I've been hearing that since the year 2,000.  I would still love for it 
to be true :)

That is pretty much what I have been doing.  I was hoping for the 
convenience of type as you go error highlighting like I can get with Java.
