I came upon this site (http://gs.statcounter.com/) reading an article about Bing momentarily being ahead of Yahoo! search. That was interesting enough, but when I checked their homepage, the statistic they lead with (and which apparently is of the most interest to visitors) is the browser share. They also have statistics on specific browser versions, operating systems, and mobile browsers.
The site has great date and geographic filtering and trending. You can download numbers as a graphic or a CSV, and you can link directly to any result when it looks the way you want, or embed it in another website.
A few numbers as of today:
| Region | Internet Explorer | Firefox | Chrome + Safari + Opera |
| Worldwide | 58% | 31% | 9.4% |
| United States | 55% | 31% | 12% |
| Australia | 55% | 32% | 11.6% |
| Europe | 46% | 39% | 13.6% |
| United Kingdom | 60% | 27% | 10.5% |
| Canada | 54% | 34% | 11.1% |
Their numbers come from stat counters on websites worldwide. They claim 5.8 billion hits per month, about 1.5 billion of which are in the U.S., and about 500 million of which are from search engine pages.
If their numbers are true, then about 3 of every 10 visitors to an iMIS website will be using Firefox, and about 1 of every 10 will be using Chrome, Safari or Opera.
An entertaining detail: in the US, Firefox usage goes up about 2% on the weekend, and IE goes down about 2%. The same was true on Labor Day, Monday September 7. (See this page.) That probably implies employers and schools are requiring IE, but people are choosing Firefox at home.
According to an old joke, programmers really only know three numbers: Zero, One and Many. iMIS W, eSeries, iMIS Public Views and iMIS 15 Casual View have marked ASI's progression of moving from Zero browsers to One. It's time to move from One to Many, and put some serious effort into making the web versions of iMIS look right and work right in Firefox. Since Firefox more closely follows the standards, the other browsers will likely be better supported at the same time.
