That usage sounds reasonable to me. :)
As to blur "having a callback"... it does. You pass in a function
which is the "callback" for when blur is triggered. For example you
could write:
function blurCallback() { alert('blurring'); }
$('input').blur( blurCallback );
Or:
$('input').blur( function() { alert('blurring'); } );
Both result in the same thing happening. Though perhaps I
misunderstood your question.

But apparently this is one.
The reason to use this technique (and I agree, it should be used wisely) is
when you have a field called "choose username" and when you blur from it, it
erases your choice, and gives a little red error saying, "Sorry that
username is taken, try again." and focuses back on the field. I have a case
for no value which lets blur happen normally.
Man, programming is hard. Thank god I have jQuery so I can avoid it most of
the time.
Feature request for jQuery:
Blur should have a callback function. Like slideUp.
Why doesn't everything have a callback?
