Yep, some went up, some went down. Overall my traffic dipped just a couple of percentage points. The days of gaming Google are over, they are no longer only looking at the things that you can control in determining your rank. My advice is quit creating pages and information for Google, and create for your users.
Google's goal is not to give you free traffic, it is to get you to advertise.
This follows one of MJ's criteria of control. If you pay for advertising you know what your traffic will be and how much you will get.
