Curious how many iPhones Apple sold in the same time frame? As a hardcore user of Echo (I have one in every room) I’ve got to say, the use cases are pretty compelling, additive and addictive.
Structured data! LinkedIn did it with professional data / profiles. Facebook did it with brand likes. And Quora came closest with narrowcasting (even going as far as creating Twitter ids for specific topics) and I couldn’t agree more, Medium could do a lot more here.
