As massive as it is, I can see Google's needs moving more towards the mainstream. Finding results beyond the first page will fall to other search mechanisms as their inertia develops into a... character. For example, it's hard to search for certain medical information because of so many pop songs clouding out results for "how the heart beats," etc. There will be more and more aliasing and hacking through keywords to distinguish between pop uses of heart and medical uses of heart until eventually people will learn which search mechanism to use for what purpose. Google will most likely ride the mainstream into the sunset, the Sears of our generation.
