I’ve been talking about the Google Panda update recently. I pointed out how it would affect your SEO, Link building, and what you can do if and when you are unjustly affected.
I agree with this article's sentiment. Just wrote about SEO being dead the other the day http://www.scoop.it/t/ecommerce-revolution/p/2249335079/6-reasons-search-engine-optimization-seo-is-dead . I also agree with the conclusion that, despite the need to learn a new bag of skills, the web and we will be better for our short term SEO pain.
