The problem, I believe, is that people are becoming less patient with actually having to think. Typing out an entire question, waiting a few hours and checking back certainly is more work than punching three keywords into a search engine and skimming the results. But it doesn't require any thought.
That is what jxpts's suggestion of putting an Ask Jeeves like stage in addresses, and if there really was a practical way to do it I'd be all for it. As is I can only think of ways to give Super Search another (or several) more promoting spot(s), where it gently but firmly pushes itself upon people. If someone has better suggestions, by all means express yourselves.
