Maybe you've heard of Pinterest ­— you know, the website "that has exploded onto the social networking scene, amassing as many as 13 million users in 10 short months," according to the infographics website Visual.ly.

(For the uninitiated, here is a description of Pinterest from the iTunes app store: "Pinterest is a virtual pinboard. It lets you organize and share all the beautiful things you find in your life. People use pinboards to plan their weddings, decorate their homes and organize their favorite recipes. Best of all, you can browse pinboards created by other people. Browsing pinboards is a fun way to discover new things and get inspiration from people who share your interests.")

If you're American and you know about Pinterest, chances are you're either female or someone who heard about Pinterest from a female — because no fewer than 83 percent of the Americans using Pinterest are females.

Across the pond in the United Kingdom, though, the Pinterest male/female ratio is startlingly different: 56 percent of the British people on Pinterest are males.

More food for thought: only 3 percent of American Pinterest users make more than $100,000 annually — compared to the 29 percent of U.K. users who earn more income every year than the British equivalent of 100,000 U.S. dollars.

A very cool infographic at Visual.ly has these and other nuggets available to view in full Technicolor splendor. News website Mashable explains the genesis and significance of said infographic: "Using anonymized, aggregated opt-in data from various Google products (including Toolbar and Analytics), DoubleClick Ad Planner has drawn some conclusions about pinners on both sides of the pond. Most compelling are the gender, wealth and interest differences between the two countries’ users."
