I have noticed that the del.icio.us classes are deleted when del.icio.us makes its daily posting to my blog. The post from del.icio.us used to include delicious-link, delicious-extended and delicious-tags. Is this something that is being stripped by WP or something del.icio.us has changed in the last week?
