1) Respect for  differences. Sandberg is an extrovert. Zuckerberg is a clear introvert. A lot of people choose to hire people who look exactly like them,” Mr. Zuckerberg says. “Here we just value balance a lot more.”

2) Loyalty - Ms. Sandberg defends her boss against his critics. She says he is warm underneath that reserved exterior.“He is shy and introverted and he often does not seem very warm to people who don’t know him, but he is warm,” Ms. Sandberg says of Mr. Zuckerberg, her voice rising with empathy. “He really cares about the people who work here.”

3) Coaching – They support each other by offering honest and direct feedback. They are not afraid to push back on decisions (ex. Ms. Sandberg disagreed with the details of Zuckerberg’s philanthropic effort) and provide emotional support. “At a technology conference this summer, for instance, Mr. Zuckerberg flopped during an onstage interview. He gave rambling answers to questions about Facebook’s privacy policies, became visibly nervous and started sweating profusely. After the interview, Ms. Sandberg encouraged him not to beat himself up over it, but to focus on parts of the interview that went well so he could do better next time….”

4) Frequent and Regular Meetings – In their Monday morning and Friday afternoon face to face meetings, they address strategy, personnel, deals and each other, according to the article. There is just no getting around sitting down face to face (resisting a pun here).   I am relieved to see these two leaders modeling good ‘ole conversation.

I have been hearing the cry of “enough already” from Introverts. Here is a well expressed example from an introverted virtual assistant.

“Much of my work as a virtual assistant involves social media these days. Initially, this was much easier for me to handle as an (extreme) introvert.  Strangely enough, I find that as friend counts climb and the volume of online communication grows, I react with the same sense of overwhelm, stress and exhaustion as I do to live or phone communications. Have you heard this from others?”, she asks.

I spoke with a social networking guru recently who told me the trend is moving away from massive social networks with random friends and towards more selective managable lists of contacts. He pointed me towards FourSquare, a cool application that lets you share places and updates with friends. This may be one answer for introverts (and extroverts alike) who want to get a handle on more meaningful connections.
