I fell in love with this within 10 seconds. Addictomatic searches the most widely used and popular live web sites for news, blog posts, videos etc. It then aggregates them in an easy-to-read personal results dashboard. You can bookmark the dashboard for easy reference. I know similar services exist - but for some reason this struck me as the cleanest and most comprehensive. Please leave a comment if you have another service that tops this.
