An anonymous reader writes: Google has announced that its Google+ social network has received a major overhaul, which is rolling out today to users who opt in. The company says the new design focuses on the "Communities" and "Collections" sections of Google+, since those were the ones most well received by users. "[Product Director Luke] Wroblewski, known for his responsive and progressive design work, tells me that the key to this rollout is the consistent, mobile first experience that hasn't historically been a hallmark of G+." The article describes the new experience thus: "As you click through the new Google+ there is a lighter feel to it for sure. It's a product with more purpose, as before it felt like there was a million things flying at you. Notifications, +1's, share buttons. You were pretty much sharing things into a pit and hoping that Google would do fun things with them."
