A very fun application I have found myself using often over the last couple of days is Stumble Upon. The premise is pretty simple, join up for free, click a few categories you are interested in, and download a toolbar for your browser. After that, anytime you want to be taken to a random website click the “Stumble!” button on the browser and you are taken to a site from the categories you have chosen (all of which are generated by the site’s user-base). I have found some cool sites using this method while killing some time, below is a feed of the most recent stumbles I liked.
