Pinterest, in the Army Now, Addresses Copyright Concerns

Pinterest has crossed the digital divide of 10 million, attracting 11.7 million monthly uniques in the U.S. “faster than any other standalone website in history” as TechCrunch commented earlier this month.

More than 100 brands are now on Pinterest, which has popped up in Facebook Timelines by more than 60% daily thanks to integration with Facebook Open last month. Facebook has helped fuel its meteoric rise as "Pin" has joined "Like" in the social media lexicon. It's so popular that even the U.S. Army released an introduction to Pinterest. So it should come as no surprise that the visual bookmarking site is standing at attention these days.

With the brand’s popularity, a rise in speculation about users "pinning" copyright-protected images has surfaced. Concerned, Pinterest has responded with an opt-out option for website owners to disable access with a metatag function by adding a string of html code.

As the Love Infographics chart below shows, Pinterest ended 2011 more popular in the U.S. (nearly 12 mm) than in the U.K. (200,000 userse). Give it time.
