You have to wonder if Google have got some sort of killer app they want to launch but IE is the problem — the sort of killer app that corporates and institutions will want access too.
I don't see that they did this to raise anti IE feeling (unless they get off on preaching to the choir).
Don't see that WAVE necessarily fits the bill but it does need proper HTML5 support ...
... not sure anything is likely to drive people away from standards compliant browsers, maybe just sites that won't render in less capable browsers.
I reckon the user would blame a poorly rendered site on the author/owner rather than the browser.
Standards are the goal, and it's never been closer. However,
interoperability is more important. Writing markup, code and styles to the standards and provide at least an accessible level of operability to the less capable user agents.
