I think Forbes recently rolled out their endless scroll to get recent with web UI standards. They're softening the blow to their less tech savvy users.
I was just thinking about this earlier today. I realized that most desktop websites were plenty readable on my early smart phones and tablets. Now, the tablet and mobile designed sites are barely usable. Some just crash the browser. The touch buttons are out of place. Mobile install rollovers block basic UI spots.
The number of sites I don't read on mobile anymore is increasing.
