Maintaining rank and attracting organic traffic from Google requires constant, continuous work, and there are plenty of ways to shoot yourself in the foot. We all compete for this traffic; getting angry at Google and writing a pissed-off blog post won't change her ranking - stepping up to the plate and competing for the traffic using white-hat SEO, semantic markup, webmaster tools, syndication through social media, etc. is the only way forward. SEO has changed - adapt or die.
