You are dress like a potato couch ? According to The Economist (not the typical geek reading) quoting researchers at Harvard Business School, published by The Journal of Consumer Research:
You’re saying, I’m so autonomous and successful that I can afford to dress in a non-conforming way.
What else ? You spent most of your meetings/brainstormings/whatever doodling with a pen on dead trees ? Guess what !? According to the Wall Street Journal (still outside of HN, aren't we ? (1)):
Recent research in neuroscience, psychology and design shows that doodling can help people stay focused, grasp new concepts and retain information.
And the last, but not the least, as a geek, you think you have very few friends, don't you ? Good news:
twenty years ago, the sociologist Scott L. Feld observed that most people have fewer friends than their friends have, on average. He called that phenomenon the «<a href="http://en.wikipedia.org/wiki/Friendship_paradox">friendship paradox</a>».
So yes my geek, you are full of flaws, but now you can disguise them as strategies, or phenomenon !
Science, helping geeks since 9000BC (AFAWK).
