From my vantage point the sprint day was extremely well attended. I spent my day working on a patch I had submitted to the Flag module and working on OG Forum and OG Forum D7.
We had the traditional live commit in the afternoon.
After the keynote I took advantage of the opportunity to meet face to face with a new contact. Then, after lunch I headed into a couple of BOFs that were way out of my league and made my brain hurt.
I have settled on using Udemy as my exclusive platform for delivering Drupal education. I'm so excited to start taking advantage of all the great tools the platform offers and I am laying the groundwork for engaging extensively with my students.
