The problem is that Google not only produced lots of collateral damage. The problem is they ditched tons of targeted seo'ed sites in favour of untargeted seo'ed sites. Or, to speak googlish, nuked targeted quality spam in favour of untargeted lowkey spam.
That is *exactly* how I feel, but I couldn't have put it into those words. In many cases, the "untargeted lowkey spam" is just noise without seo.
I'm unhappy with the results as a searcher and actually using that alternative .org engine when I want to find something.
