I posted similar DD last week and was downvoted to hell. Basically said Pinterest will make money by lying about their users. I wont touch the stock but I doubt it will go down until about 13 months from now when their first user/data scandal hits.

I legitimately cannot see what possible revenue Pinterest can generate that would make it an attractive stock to own and hold. 
  
 Sure there are similar entities to it and social sites, but they do what Pinterest does better.
