We're so obsessed with [big] data, we forget how to interpret it.

For higher-level execs with greater public visibility, social networks need to become as good at filtering as they are at connecting.

LinkedIn is very good for browsing relationships and hooking into your contacts' networks. It re-connected me with high-level execs I hadn't talked to for some time, who then helped me close various deals.

Social networks are like grease - in some cases, gasoline - for our personal business networking machines. If you aren't plugged in, you will be out-done by better-connected, hyper-networked colleagues and competitors.

Privacy is not a static construct. It is not an inherent property of any particular information or setting. It is a process by which people seek to have control over a social situation by managing impressions, information flows, and context.

And I think that’s a lot of the reason why when you start to fragment your audience, you start to think about what you’re looking for, you’ll go to different spaces, and it parallels what we do as adults. You go to different bars when you’re in the mood for different things. You see different people when you want to go listen to music or when you just want to have a quiet drink with a couple of friends.

Neither privacy nor publicity is dead, but technology will continue to make a mess of both.
