[wp-hackers] get_user_meta returning empty string

[Otto]

Oh, and BTW, the global $current_user is already an instance of the
WP_User, for the current user. So if you're talking about the current
user, then you can either just use that global directly, or do this if
you don't like using globals (I don't):

$user = wp_get_current_user();
