I really like the main message of this video. I think it makes loads of sense, I've employed it in my own projects at the beginning. One question is that it seems like the first speaker and some of the people asking questions are asking "why did nobody ever do this before?" That just isn't true. In Atlanta, for instance, we have had a company Zifty for years. Zifty has been here well before grubhub or the other sites. I guess Zifty hasn't expanded to San Francisco, yet. :) But anyway, my point is that I don't see how doordash is a new idea? Edit here's the question from the transcript: Q: When you started, it seemed so obvious to you, you were wondering why, what the reason was nobody had done this before. What's your answer now looking back?
