More tips from @AlSweigart on gamifying social interactions for yourself while at @pycon:
• Pick a color besides black, grey, or blue and find the closest person wearing a shirt of that color. Go up and talk to them, no matter who they are.
• Try to sit at breakfasts and lunches with people you don't know.
• Try to avoid eating alone. Meals are a great time to meet people.
• Try to follow up with folks you met after Pycon.
