Matt Cutts and Amit Singhal Share Insider Detail on Panda Update
...we used our standard evaluation system that we've developed, where we basically sent out documents to outside testers. Then we asked the raters questions like: "Would you be comfortable giving this site your credit card? Would you be comfortable giving medicine prescribed by this site to your kids?"
There was an engineer who came up with a rigorous set of questions, everything from. "Do you consider this site to be authoritative? Would it be okay if this was in a magazine? Does this site have excessive ads?"
...we actually came up with a classifier to say, okay, IRS or Wikipedia or New York Times is over on this side, and the low-quality sites are over on this side. And you can really see mathematical reasons.
Regarding improved results: I am sure if US drops 100 nukes in Afghanistan and Pakistan they will kill many Taleban, along with
I was reading an article from CNN on Panda's $$ impact and decided to google a direct quote to see if others were discussing it. #1 came a scrapper, CNN second, and the CNN article was copied 100% there. I will post the link if I can find it, maybe I was logged in, but even then, CNN should have come first since I was there, no?
Take a look at some unfamiliar competitive SERPs- try a few keyword combinations. Some things hit you
a) YOU do not know who published first
b) Top results are differentiated offerings
c) There are very few sites returned which look like total dross
before you say 'they should (blah)' go try and do it
I read this idea here a few days back and I think it's a better solution to the scraper issue. when you publish something new, you don't post it publicly immediately. First you ping google, and wait for a signal of some sort, that G spidered your new content. If it agrees with you that it's new and original, it sends you a token. After receiving it, you can make your content public knowing that G is aware that you're the original source.

What I do not understand is the following: They say they cannot reveal information about the update because it would be gamed. But what would be the consequence if everyone knew Google's definition of quality? Right, everyone would modify or create sites based on that standard, at least if they want to rank in Google.
