Ooohh I see. Where else is GUID used? I suppose the only requirement is
that the GUID be universally unique. Which means I shouldn't use slugs at
all because they could be reused on a different blog. I guess some
combindation of the lyceum installations domain name and the post ID in
the database would suffice?
