I haven't weighed in on Panda topics lately. I will say for anyone to take opinions as "gospel" should rethink. Greg summed it up best. I can't add to that.
It's a waste of my time reading this. The solution is to assume Google will cut your organic at some point. It called moving forward and assuming the worst regardless of whether you consider you site good or not. It's like the plague. Take a number and hopefully yours isn't pulled.
Pretending to come up with a Panda playbook or following someone elses playbook is a waste of your time. My opinion of course. Moving forward I'm assuming nothing. The only real credible solutions are with what Google releases about Panda. That's it. The biggest potential waste of time and money is hotly pursuing the Panda solution. Wait it out. Perhaps then Google will give up some of the search market and Bing and Yahoo will stabilize your organic. I realize a lot of people aren't able to launch something new and are stuck. Tweaking and tearing up based on a few people's opinion? Rethink that.
