From Lauren Indvik at Mashabole: Pinterest, a two-year-old social book­marking site that lets users collect and share things they like on the web, is driving increas­ingly signif­i­cant amounts of traffic to retailers’ websites. The service enables users to create online bulletin boards, or “pinboards,” for popular cate­gories such as home decor, food and wedding inspi­ra­tion. Members can use Pinterest’s “Pin It” book­marklet tool and iPhone app to save things they see online and offline, and explore and repin the images their friends collect via their personal news­feeds. The website is espe­cially popular among women, who account for 58% of Pinterest’s traffic, according to Experian Hitwise. · Go to Pinterest becomes top traffic driver for retailers →
