Re: re: Not a defence, it's not difficult to make things work cross browser.
Personally, when I use an unsupported browser, I don't care what the site looks like. If I render tables, side panels and transparencies wrong, I know the blame is on me. On the other hand, if they just refuse to provide a page at all, that's a problem, and it sucks.
jQuery started out offering transparent support for multiple browsers, then, as you no doubt know, later choose to interpret 'does not support' as 'will deliberately break support for'. So that when using an older browser you would get a blank screen on sites using current versions of jQuery.
jQuery pioneered "break site for unsupported browsers".
