IE9 is actually more standards compliant than any other browser. However the misinformed often spout the nonsense about Google Chrome being the most compliant when in reality it is now far behind IE – and the biggest sinner is now Firefox.
The above is confirmed, independently, by W3C. Full report here: http://test.csswg.org/suites/css2.1/20110323/report/results.html
This blog post also explains the report results: http://blogs.technet.com/b/uktechnet/archive/2010/11/02/internet-explorer-9-the-most-standards-compliant-browser-on-the-block-a-guest-post-by-simon-may.aspx Although it is a Microsoft blog post all the author is doing is quoting from a WC3 report.
So please stop publically saying that IE is inferior. People are being badly mislead by the incorrect popup message you are displaying on your website.
And no, I don’t work for Microsoft but I do find baseless misinformation to be annoying, and there is plenty of it from “experts” on the Internet.
