They're ids, not guids. Certainly I would expect that there'll be
some accidental conflicts. For instance one site might number its
posts post1, post2, post3,...; and a different, unrelated site
might do the same.
No, they are guids. The datatype for an id is a IRI, which is a
generalisaiton of URI. IRIs are constructed in such a way that it
should be easy to construct universally unique ones without ever
having name clashes. If name clashes there are, this will either be
due to incompetence or to malevolence.
