It is always great to get a chance to hear Yehuda present and this was no exception. Based on the description of the talk I was expecting more interaction with an existing app and the addition of new features, in hopes of picking up some tidbits I might not have already known, and not so much of the content at the beginning. Don't get me wrong - it was great content, it just may not have met the expectations of others as well given the description. And I did pick up the feature flag component idea :-)
