The Internet is essentially infinite in its growth capacity, so you don't need to worry about clutter. People don't normally find what they're looking for by trying to sort through the entire Internet anyway.
I found New York City pretty cluttered when I visited there, but I was still able to get around just find, see what I wanted to see, and meet some interesting people.
It isn't hard to rise above the clutter once you figure out what you're doing. You'll eventually pass through the clutter if you just keep learning and growing as you go. The clutter-creating people aren't in it for the long haul.
It doesn't matter if a search returns a thousand results or a million if you're in the top 10. Most people have no chance of reaching the top 10 because they don't offer anything worth finding. If you can offer something more valuable to people that what shows up in top 10 results right now, you're putting yourself on the side of Google and its users -- they'll actually want to shove you into the top 10 because you deserve to be there.
