As an adwords user, this is crappy. I do not want free untraceable clicks, and I don't think people should screw Google over. Just like adblock, I believe that if you don't like something, don't use it. Don't hack it around into something else and just leech the stuff you want. That's hypocritical and dishonest. Does it just take you to the 'display url'? If so, it's also pretty pointless - most people can type.
Convince Google to take privacy more seriously and you may have a point. Until then we have no choice but to use tools like this to at least attempt to filter what is recorded.
And the "most people can type" comment is silly. Why have links at all then? Let's just type everything.
