Some days I stare at my monitor and wonder where I might find a glorious art site to inspire me. Then I remember my free subscription to StumbleUpon. It seldom disappoints and often entertains and inspires. Here's how it works. When people discover an interesting site, they recommend it to StumbleUpon. When you sign up for StumbleUpon you list your interests (arts, photography, gardening, science, politics, etc.) and StumbleUpon sends you those recommended sites periodically or you can search them whenever you want. Here's the link so you can explore it yourself.
