My my. Two groups of system-defined and managed "cross posting slugs" (for reBlog goodness via slug-based RSS extraction1), author specific "tags" AND suggestions, based on all three arrays.
You, whoever coded the del.icio.us tags UI on the post page, I kiss you. :*
[1] I'll explain this some other time, but basically I am going with reBlog in this case because it does full attribution AND makes sure you don't post the same item twice. Otherwise I would have used the Atom API. Oh and because Michal is a really ace dude, awesome techhead and designer.
