If this is indeed the real motivation, the next obvious target would be bookmarks. What can be done about them? Replace the bookmarked URLs by Google queries? It would be an interesting functionality if Google could look at a page and give you the smallest query that would have returned exactly this page as a first result. Then bookmark the query instead of the URL. And if the search results change in the future... I suppose, it would be possible to spin this as a feature. ("Self-improving bookmarks" perhaps? You don't have to worry about link rot; with latest Google self-improving bookmarks, your bookmark will always point to the best existing page on given topic!)
