This looks pretty good overall Carl. Was there specific problems that this redesign is trying to solve? I guess I am trying to get in your mind a bit. I am not sure what type of data or feedback we currently get about the KDE site...and how this is going to be easier/better for people. That helps with decision making a lot -- especially when there are disagreements with what to do or not to do.
In terms of piwik and web analytics, I could go either way. Do we care if people are trying to access this on their phone? Are there many people trying to view this on a 4K monitor? For this KDE site it might not matter, but for applications it can be really important. For example if most people that are going to your site have a 1366 x 768 monitor, you better make sure your application works well at that screen size.
