I have an off-topic question: After seeing their brand new buildings in SF in SOMA area, I’ve been wondering about the Pinterest’s success lately. Does anyone have any resources talking about their current trends, numbers and their business model? Honestly, I lack the context, because I was so annoyed by their spam on the Google’s search result pages that I started to use queries with -site:pinterest.com. So, to me this is completely irrelevant website.
