At the moment I got around 25-30% of mobile and tablet traffic with my responsive site(s). Page views tend to stay around 3.00 per visit, bounce rate around 30%, session duration around 01:52. I'm seeing no difference in behavior between different devices.
I'm very happy with the layout, it's easy to read even on older phones with 4.3'' screen such as mine, and the site actually looks best on tablet. All the content is present in all versions.
Obviously the visitors are happy with the mobile versions of the site, otherwise their behavior would differ from the desktop users. In your case, Gooner, the visitors are likely very motivated to read the content because they're return visitors who already know your site.
