Go for it. Maybe it wasn't that excellent :-)
One could simply write:
$('a').click(function {
this.blur();
});
That way it should work identically and you don't have to pollute other
handler functions with $(this).blur() ... The only difference is that
you loose control here a bit over when blur() is called in comparison
with the other approach.
