when i lived in Tokyo, occasionally i attended the Tokyo Pecha Kucha Nights:

What is Pecha Kucha Night?

Each presenter is allowed 20 images, each shown for 20 seconds each - giving 6 minutes 40 seconds of fame before the next presenter is up. This keeps presentations concise, the interest level up, and gives more people the chance to show.

how about have a EuroTrib Pecha Kucha night (or day) at the Paris meet-up?  we can tweak the requirements (e.g. images optional, different time limits, etc.) as we want, of course.  the main idea is to have a format to elicit interesting talks and discussions in a creative fashion.

(Pecha Kucha nights happen in cities around the world.  if you want to attend one, you can check if your city has them on their website: Pecha Kucha Cities)
