BlockPlus will remove any links to Google+ in the global nav, including the profile link, circles, etc. It will also remove the notifier. It blocks the requests, and also hides those elements from view - so you are not only hiding it but saving on 6-7 HTTP requests that normally take place each time you hit the global nav.
