Annotation itself is great, but there are other (unsolved?) problems - I just recently came across this very implementation thanks to a HN comment - after trying it out it suffers from not being able to tied to revisions of pages - install the plugin and go to the home page of any major news outlet - there are comments from years ago - that works fine if its a news article - but not on a page that changes every day if not hourly. Also to get rid of comment widgets on pages you need to be able to subscribe which I don't see any way of doing.
