I recently exchanged posts with an OTN member about the support (or lack thereof) of the Opera browser in Oracle Website infrastructure. (Read the thread here; login required.)
During this process I ran a report on the browsers and OSs used by OTN visitors (vs. Internet averages):
Browser , Percentage , Internet Avg
IE 6.0 , 69.3% , 75.8%
Firefox , 22.7% , 8.6%
Mozilla , 2.2% , 0.5%
Opera , 1.5% , 0.3%
IE 5.5 , 0.8% , 0.9%
IE 5.01 , 0.8% , 0.3%
Netscape , 0.6% , 0.3%
Safari , 0.4% , 2.6%
OS , Percentage , Internet Avg
Windows , 67.0% , 75.7%
Win2000 , 24.5% , 10.1%
Linux , 4.4% , 0.3%
Macintosh , 1.2% , 7.4%
Windows 98 , 1.1% , 3.8%
Windows NT , 0.6% , 0.4%
SunOS , 0.3% , 0.0%
Windows ME , 0.2% , 1.7%
Wow, look at those FireFox numbers! And OTN members clearly are not visiting from their Macs at home....
