95% of people never click past page 2 anyway.
Google's brand has the aura of an unlimited wealth of information. People don't even see it as a means by which they search anymore. When they say, "I found it on Google!" the website they actually found 'it' on is completely irrelevant.
However this note I found at the end of the list of search results destroys this aura. It makes you think, "Oh yeah, Google is just a website with a finite capacity to serve information."
