Saving bandwidth and processing power.

Think of something like Bugzilla. Every time anything is changed or a 
comment is added, the entire form is resent--but usually only one or two 
things have changed. Not only does this use many times more bandwidth 
than it needs, but at the server everything has to be compared to see 
whether it's changed or not.
