I absolutely have seen a decrease in quality. I used to be able to use keywords to divide the search space very effectively (ie "programming language" "concept" "version"). Now it seems that Google is concerned with over fitting and they've relaxed the power of each keyword to filter results (sometimes ignoring them altogether). The end result is I tend to get articles that are more general and it's difficult to get a highly detailed forum post or blog anymore.
