If you honestly do not think anything has changed in the last 8 years then you should take a step back and reconsider.

Long gone are the days of stuffing the meta keyword tag with the same word and now you need to grasp the concept of multivariate analysis.
You may not be happy about Panda. Your anger & frustration might make you want to rant and complain. That achieves nothing productive. What is productive is to look at the Florida update and ask yourself how did impacted webmasters rebound? Will those changes help me with Panda?
Of course it is a free world and you can rant and complain but while you are doing that I am adding more pages to my site based on new keywords I found using Google suggest, launching an email newsletter to boost direct traffic and make me less reliant on Google, and interviewing college professors to gain relevant one way .edu links from their university bio page.
