My first Drupalcon. Actually my first Drupal community event. Here's what I think you have missed.
I was impressed with the vibrant community of developers, digital agencies and business owners. A lot of content was provided in different tracks, both business oriented as technical deep dives. Drupal trainings were held and there was a lot of active contribution happening at the event. It was so good to see our talented and super ambitious team host several sessions, and obviously it was great fun to be in Amsterdam with the team for the week!
