Just my two cents if I may --
Before Penguin, I had two screamin' demons .. two sites that listed very well for a very long time (since around 2004) .. they blew thru the likes of Florida and other updates without so much as getting a speck of dust on them .. After Penguin, both are on life support .. limping along like a couple of whupped-up-pups. The PR is still there, but the SERPs suck with the biggest lips I've ever seen for the both of them.
I've launched 3 since the Penguin, 3 new domains, all with similar content, style and builds that the old ones had .. New ip's and servers .. Two of them are actually doing better now than the other two did before Penguin -- Two of them have actually gotten a bit of PR too. (I've dumbed down, or otherwise simplified the content on the new sites however with an eye toward the casual reader/visitor)
I've decided to let the other two pre-Penguin limp-alongs languish for just a while longer before I park them to die a peaceful death --
