Search Trends - Search Engine Marketing

Google unveiled a new personalized search feature through Google Labs. It's not 100% clear how it works, but apparently it uses a profile of basic interests that the user creates to customize the results by relevancy to the users' interests. I'm not sure how well it will actually work in a practical day-to-day search environment, but the concept is definitely interesting. It could have some practical applications. I like how it has the sliding meter that lets you personalize the results more or less depending on just how personalized you want the results to be. It also has a little graphic to show you which results are intermingled with the "normal" search results. Some search queries I attempted yielded no personalized results. It said there's not personalized results available, but it gave the option to edit my profile.
