I would, so if you wanted to add extra info about the user down the road that data will be abstracted. Since you are the only user just pass 1 to user_id. or if you want to keep it real simple just add id (index, auto increment) to the read table.
CREATE TABLE IF NOT EXISTS `read` (
`id` tinyint(8) NOT NULL AUTO_INCREMENT,
`title` varchar(250) NOT NULL,
`url` varchar(250) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
