I was reading
del.icio.us documentation which insists that the service is all about "social bookmarking". And from the perspective of browsing the del.icio.us site to find bookmarks that are tagged in specific ways, that's true.
But from the perspective that the bookmarks are associated with semantic information about the page they bookmark, and given that there is a bookmarklet interface that allows you to see that semantic information when you are on the page in question, they start to look truly identical to
annotations. (and if del.icio.us doesn't serve their bookmarks as annotations soon then shame on them)
