Check out this blog post about Google Penguin 2.0 the update to Penguin said to be coming about next week. What do you think about it, what do you think will actually materialise. http://blog.fourquotes.co.uk/what-is-google-penguin-2-0-how-will-it-affect-my-site/
Let this come, I also heard this news, and I'm trying to follow what it wants lets see what happens..but I have prepared for this.
I think this is the best attitude to have. Google is not out there to analyse quality content. Most genuine webmasters should embrace these changes. If anything it will result in a higher ranking as it removes the junks from above them. Keeping a site up to date is also important.
