Putting up photos and posters of your interests has been going on in teenagers’ bedrooms and locker doors for decades. Pinterest extends this concept into the digital age.
The visual appeal is key to understanding Pinterest. Twitter is extremely text heavy, and, while Facebook certainly has visual appeal, it’s not as clean and sleek. Tumblr can be configured as a photo sharing site, and, indeed, some of the most successful Tumblrs do this.
I’m not entirely sold on the concept of Pinterest, but I do think its nascent success speaks volumes about the power of images.
