There’s one massive problem in the social space: everyone is competing for the same user time. But most services compete by piling on features that erode that time even quicker. They’re offering up services that if I use, it means I’ll have even less time to actually enjoy life. That’s not a sustainable model. Being “social” online has become far too much work. Facebook has clearly been thinking about this problem. And now they have a way to tap the power of social without thinking about it. That’s the future of the space. It’s not about needing a share button. It’s about not needing a share button.
