Will www crash on itself due to too much information?

What do you think? Will www ever crash on itself due to too much information? I’d say yes, because once there was 1 website, del.icio.us, then came digg, and now I see more than 10 websites doing the same link sharing thing… Same with everything else. For video, YouTube, then came a lot of other websites that do the same exact thing… Doesn’t this just overload everyone?
