Bookmarks and annotations

Bookmarking a page is a lot like annotating a page and can be combined by combining metadata and filtering with different viewers:

bookmark	annotate	bookmark&annotate
goto a document	goto a document	go to a document
bookmark a document	annotate a document	bookmark&annotate a document
select categories	-	select gategories
-	present annotation as an icon on the page	present bookmark&annotation as a bookmark icon on a page
present bookmark as a link incategory hierarchy	-	present bookmark as a link in category hierarchy

Are AnnoSpam annotations annotations of type:bookmark or bookmarks under topic:spam or both?
