One of my new favorite "toys" is Stumble Upon. I added it a while back, but never really gave it much attention. Now I find it very addictive and interesting all the same. It's a great place to generate ideas and gather new one. The concept is simple actually. Once you register, it asks for you to select categories of interest. Then it adds a navigation bar to your browser with a lead "stumble" button. Click to get a refresh of content either randomly or by categories that you selected in a variety of formats - video, urls, images, etc.
