I enjoyed the latter half more. I think cutting the pitch down to 5 minutes and diving deeper into the lessons learned along the way could bring that talk up a level.
The graph he presents has a blue line which demonstrates number of people in the system (100% today, 0% 250 days ago).
The pink line is the total revenue of everyone using the ad service on the 30/31st day divided by the number of signups 30/31 days ago. If the curve starts declining, why is it declining? Does the advertiser need to be pinged with email every week? Etc. So the goal is to make sure the curve asymptotes early on so you know it is a viable business. You could imagine Facebook trying to sell apparel with "FACEBOOK" on it and the retention curve would decline; not a good business.
After this he begins to talk about growth. You can’t have growth without first identifying product/market fit.
Not saying that FB's growth approach is better than Google's - I'm just not sure why the dismissal.
