8/ It was a fun and educational evening, thank you everyone!

The only negative was that we had to limit attendance due to the size of the venue. We need your help to find larger venues for future events. Please let us know if you can help!

Our next Berlin event will be on 🗓️ Wednesday, 22 April - sign-up is open, we still have a few speaking slots to be filled. Please volunteer.

5/ Benjamin Trigona-Harany was our next speaker and he gave a very entertaining talk about his hobby project of mapping Ottoman transportation networks. Lots of beautiful and interesting old maps in this talk.

The audience later awarded this talk the SplashMaps best speaker prize 👏👏👏

2/ Our first speaker was a Dave Whittingham (a past best speaker winner!). Dave returned to share his story trying to build a basic, map-based travel sharing tool for a cycling trip.

Unfortunately good intentions don't always yield a great product, and he shared lessons learned with us in his talk.
