I read the article top to bottom and couldn't figure out what it is that Hall does.

> This startup is interested in building what comes next after the “social intranet.”

I don't know what the social intranet is or was, I certainly have no idea "what comes next" -- and the article doesn't say.

> At Intuit, Hellman was the only person on his team at the Mountain View office, which led to the original inspiration that later became today’s Hall. “That’s where I learned we needed a better way to communicate,” he says.

What was that better way??!? Better than what? He doesn't say.

These "articles" don't try to inform, they just throw buzz words around; they are instruments for companies to do PR, but the reader is the victim.
