Ok I'll bite as this is near and dear to my heart. Instead of showing me a fast webpage with a minimal content, tell me how to make my tons of css and js load fast! That's a real problem.I deliver web apps, and interactivity is a must.
IMO, the real problem with the web is the horrendous design choices and delivery of very popular news and daily reading sites (ahem cnn) where subsequent loads of ads and videos start shifting the page up and down even when you have started reading something. Let's address that problem first!
