What sites, e.g. experts-exchange.com, would you remove from Google?
jacquesm: All the stores that have been spidered
  (amazon.com etc)Googles own sites
  (youtube.com, images.google.com, etc)All the cloaked sites (sites that will redirect you after landing, or that show you different content than they showed the search engine)All the spammers
   (you've already mentioned experts xchg, but there are many many more)Anything that points to or contains the word sedoparkingAll the crappy blogsI'm sure that google could do with several billion pages less than they index right now and their quality would shoot up.
