The original PageRank hasn't been used for a very long time-- the current system is a lot more sophisticated and blends many different ranking algorithms. I think that Google has done a good job of adapting to both the changes in web content and SEO scams. I do occasionally see noise in my search results, but there's always something useful among the top 3 links. This is quite different from the bad old days of Altavista, where you could get pages of outdated or irrelevant garbage.
