It also has better network-effect than say Uber (which has per-city network effect but no significant global network-effect) and less competition than latter. The "moat" is super strong and the leadership (Brian, Joe et al.) seem to be really good.
I'm so in awe of their prospect. My only misgiving is that they rejected my application (which proves no one's perfect after all - as they seem to also make hiring mistakes:P)
