I'm in the middle of mining data, but I've got enough to give a summary of some stuff that's going on. Across all the big article directories, there's an average loss per page/keyword of 35 positions. These sites got hit hardest out of everyone. EzineArticles, GoArticles, ArticlesBase, Buzzle, all those guys. No exceptions. Hubpages lost an average of about 30 positions but squidoo lost only 15. This might be some kind of good hint. AssociatedContent got off a little easier, lost an average of 20. Livestrong is up 15, epinions is up 15 as well. Etsy is way up with a +30. I think they were the biggest winners in this update. Answers.com, Investopedia and sites like that got hit really hard too. I'll post real data later for anyone who wants to see. I'm collecting as much as I can right now.
