gnosis' arguments seem worth refuting. I can see how someone outside of Google would assume that using 4000 machines to scan the Internet on some whim would be a big deal. But at Google, it's not. That's why working at Google is so cool.
I'm saying somebody who blithely asserts that Google is just "about how I can get people to click more ads or make more money for some trendy corporation" is a troll and not a comment worth responding to.
