The topic really is totally general interest. There should be no bias for browser there.
I do have a section for school kids (quizzes). I was thinking that institutions (schools) might have a bias for Apple. Actually I found the contrary, plus traffic in that section wasn't heavy enough to influence my site's totals anyway.
I also looked at direct traffic, thinking the bias might be, once again, my site being some type of institutional, continually used, reference source. But that doesn't seem to be the case.
The effect seems greatest on my most trafficed sections, ones that should have no bias at all.
My bounce rate is higher for Safari users. As I mentioned, I don't have a mobile version and I use some Flash, so a lot of mobile Safari users could explain that.
I guess what's disturbing is to realize that I'm not catering to a large portion of my traffic.
As an explanation for a mobile bias, is there some way you can be positioned better in mobile search than desktop search?
