Pretty much the only time i use it is form processing... so i don't get a
bunch of errors when someone doesn't fill out a (non-required) field..
Also i use it to prefill form data is i have a session running, ie.
<input name="fname" type="text" value"<?php echo @$_SESSION['APP']['fname'];
?>" />
like others have mentioned... if there is no value, the form is blank,
otherwise the value is used as its defualt value... pretty neat!
