Google is now offering a personalized search service. Once you have filled in your profile data you can start searching with your profile directing the type of results that you will be proposed. Though you may be puzzled by what Google turns up when you carry the slider to the maximum personalization level, be aware that the service is in beta testing and that it may work much better on certain types of searches than on others. Not always what you select in your interest profile has a clear effect on your results, and to get a liitle more insider info on this I suggest you carefully read the Google FAQ on this new service and provide your valuable feedback and ideas to their public discussion forum.
