 * the php-documtation says, that serialized data would better saved in blob-fields
   as in text-fields. ([http://php.net/manual/de/function.serialize.php](http://php.net/manual/de/function.serialize.php))
   
   The wp-tables wp-options, wp_postmeta und wp_usermeta uses mysql-field-type longtext.
   Wy not blob-fields? Thanks,
 * Rudi

 * Just IMHO, nothing official. I think it is a legacy data arrangement from ages
   ago when WP was really just a blogging platform and not a CMS. I’m not sure serialized
   data was even used back then. The problem now is that updating the DB schema 
   would break many old legacy sites, so we are stuck today with a DB design that
   was valid decades ago.
