wow this was really good. i like  @jack mallers 's analogy and perspective. I don't think I have seen one where  @jack was the moderator and the questions were great, required a deeper thought process (for me at least) and definitely broadens perspective. I really liked the question on understanding why big companies are not adopting, signal is another example. Also on what attracts tech people to join in, and how to differentiate businesses on open source. Everyone had great input.
