I think microsoft had excellent timing with its 'scroogled' ads. (http://www.scroogled.com/).

I've already switched by browser's default search to http://duckduckgo.com, and honestly haven't noticed a difference, although alot of my searches are already on more domain-specific sites like stackoverflow.com so I bypass generic search engine.

Now, it could be time to switch back to firefox from chrome, esp. if google decides to scroogle AdBlock Plus from the Chrome Web Store too.
