My primary domain doesn't see enough traffic to really use it as a test... but EWIUSB.COM does. (five people a day take the time to fill out the contact form! I really need to add a forums)
This is excluding known spiders, is for March, counting 40,987 unique visits.
..IE9 : 3.6%
..IE8 : 5%
..IE7 : 9.4%
..IE6 : 11.1%
..IE5 : 2.2%
(IE5 is probably a few people I know with older phones -- since IE6 was "new" on Win mobile just three years ago -- deathshadow.com shows IE4 visitors, though I suspect that's the retrocomputing folks on their Windows 3.1 boxes!)
You know, that's actually disturbing -- IE5 seeing two-thirds the visits I get from IE9.
(most of that is FF11, though 3.6.15 seems to have 1.6% overall!)
(Being I'm a opera user and advocate, I'm probably skewing that number)
Opera Mini: 1.9%
Looks like I really need to put the rewrite into deployment -- hadn't really bothered looking at my stats in a while, (hell, I've not updated the content in two years) and was unaware that I'm starting to see as many people visiting from mobile as I do from Safari.
You always have to ask yourself "are the low numbers on ____ because there aren't that many people, or is it because they're bouncing with it broken?"
Out of curiosity what domain are those numbers for, or is that server overall? How large is the sample pool?
