Pinterest is rolling out a shopping bag, buyable pins on web, visual search with your camera

Pinterest, the startup whose app lets people pin photos and other content to boards and even buy things shown in pins, today announced that the buy buttons that first appeared on the app are now coming to the web version. The startup is also adding a shopping bag that will follow you across devices. Pinterest introduced buyable pins last year, and today Pinterest president Tim Kendall demonstrated the updates for reporters at a briefing at Pinterest's San Francisco headquarters. The bag is a modern implementation of a shopping cart -- no longer will Pinterest exclusively be letting its partners handle purchasing. There's even a new Pinterest Shop, with sections for Top Shops from vendors, Pinterest commerce product marketer Amy Vener wrote in a blog post.
