I don't like how inaccessible HTML5 and CSS3 techniques are to older browsers. It reminds me of having to upgrade flash.
I like how we try to make sites accessible for the blind, regardless of their usage stats.
I don't like how we seem to throw away 1% of our best possible conversion rates, by fully ignoring 1% of our audiance.
I like how the web is maturing and growing.
I don't like how plain and simple information-providing websites are turning into HTML5 applications, with 100k's of javascript, hashtags and other dynamics.
I believe that in 20 years, sites that were build to render on IE6, will continue to render just fine. Sites that were build using experimental browser vendor-specific code, with AJAX and hashtags might need a special server to render. Is that progress?
EDIT: seems to be some confusion about "Sites build for IE6". I ment "Sites that render on IE6/were build with IE6 in mind". To me that doesn't auto-translate to active-x, MS-filters, conditional rules, IE7.js and CSS hacks, but I can see how others can view that. Anyway, I am clearly playing with fire, by taking these views on IE6. I'll just let this be and not delete it. It wasn't a troll or a flame, but this topic is always a heated one, so best to just let it be.
