A neat collaborative project sprung up last week, initiated by antischokke. Eltern in Berlin is a 6-page listing of parent-friendly outings, restaurants, and tips for visitors to Berlin. Hosted on a Pirate Pad, the Eltern in Berlin listing not only gives you great ideas for Berliner fun,  but it also demonstrates how powerful quick, low-barrier collaboration can be. Within just two or three days, the Pirate Pad exploded from just a few questions into a must-see directory of wonderful things. See anything missing? Feel free to add to it or check it out when your ‘rents are in town!
