StumbleUpon is the easiest way to discover new and interesting web pages, photos and videos across the Web.
This is a great website for loads of different reasons. The reason I love it because you can follow a wide variety of different interests like business, sport, space, trading, education and more. Then click the stumble button and it will show you blog after blog, website after website of information about your interest.
I use it to find new ideas to write about all the time, then I can like that idea and it will be saved for future reference.
