Here is a picture that explains everything I experienced at this conference:
I received love, motivation, fun, feeling that I'm doing right, passion, energy, and new ideas. But most importantly I made new friends.
The topic of my talk: "We all love Open Source work and Pomodoro will help you to hack on your beloved babies in a time-boxed way to get more done in less time."
You can find the slides on speakerdeck.
