Over the past year, I've noticed it takes ever longer for web pages to load, especially if they have graphics such as ads on them. I find myself occasionally giving up on a site and going elsewhere.
I'm guessing that with ever more sites containing graphics and videos, and ever more people downloading and uploading big graphic/video-filled files, surfing will slow further.
Unless breakthroughs in Internet infrastructure occur--such as wider, faster pipes--is it possible that people will start to use the Net less?
With billions of dollars of ad revenues at stake, I'll bet that, even if we're in recession, solving that problem will be among the most high-priority and lucrative. So, techies, consider focusing your efforts there.
