Use StumbleUpon

StumbleUpon (SU) is an internet tool that brings you to random sites based upon your interests. You can also specify a particular interest category while also limiting the results to videos, photos, news, blogs, etc. SU is the best way to discover awesome content around the web, much of which you didnt even know you were looking for, As you go through and Thumbs up or thumbs down different web content, SU learns more about your interests and returns more accurate results. I also call it the Serendipity Engine because of the countless times Ive been thinking about a problem or looking for something and then the answer has come randomly to me through SU.
