I just discovered this new website called Olioboard, its a great program that allows you to create mood boards. I have used Polyvore for a while now, but I thought I would try Olioboard and compare the two. I personally find Polyvore easier to use but I'm sure once I get used to using Olioboard it will be fine. Olioboard seems to have more items to choose from than Polyvore and is more focused on design. However, keep in mind you can add your own pictures on both of the applications if you want to add something to the board you already have. Here is one I created today and I was happy with the result.
