you live in denial if you think that facebook, twitter or gmail works in opera as in other browsers.. go to sitepatching blog and see what issues are with opera on these pages, and most of them are due to opera’ own decisions/bugs
opera users for years lied to themselves that 90% functionality and some bugs there and there on a webpage is OK and that it means ‘works’. while other browser’ users enjoyed pages in their fullest. run some other browser, even IE9 will do and see the web as in 2012 not in 2005.
how is your scrolling with opera? and position: fixed? does it work? probably youll say it is. contrary to what opera themselves said :)
bullsh.. about w3c and coding standards. the same way you can make a car that would run only on smooooth as silk roads and on gas with absolutely no pollution. good luck with that, but hey, opera is trying for years to do that with spectacular result of being completely ignored by ALL major webpages
