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.

There's nothing native about young people's engagement with technology.

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

What happens online is you are constantly dealing with invisible audiences.

Business culture operates differently in different cities around the world. But I don't think it's possible to design one system that incorporates all social norms for networking. Human beings are just too diverse.

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

The things that make us safest from others make us least from ourselves.
