I am really only intrested in the new pages getting hit, but yes it does help the older pages as well get redated. I will add this and I don't have an snswer as to why but all of our sites I manage didn't get hit with this change. I have been beating my brains out trying to figure out why as we are copied by other sites but for some unknown reason right now I don't have an answer. I do know I am building a new sitemap for our sites we are adding new content, and just reading through all the post this hasn't been brought up. I doubt this is an answer but heck when your drawing straws might as well get them all in the pot.
