Quite a lot seems to have changed, indeed. Can't say it's much of an improvement as I still see some of the familiar big bugs [webmasterworld.com]. A search for a keyword that supposedly returns 2.5 million results gives me 10 listings on page 1, 0 on page 2, 1 on page 3, 2 on page 4, etc. As also mentioned in that topic, on some results pages they are still consistently displaying only pages that had the keyword as the only word in their title. Not a big overhaul in that respect, but there have been soms shifts in terms of ranking (where rankings are 'normal').
