"60 hours to code a search engine", sounds like someone is spending daddy's hard earned money at a high PR agency. Nothing solid in this article at all. This made me LOL - "It understands what a user would like before it serves up the results by dwelling deep into the content of the text, understanding the underlying meaning"
Because its true in so many of the larger Tech companies. Corporate nepotism, intense co-worker competitiveness, and inept middle management. I'm surprised everyone is so surprised.
I'm curious if you writing a "mobile app" that works in the browser, why you labelled it Android/Ios? I do love the optimism abound that you think your app will need to scale so largely. It is better to build in scale from the beginning, rather than as an afterthought.
