Digital scrapbooking startup Pinterest has influenced numerous companies to reimagine the importance of photos over text. The San Francisco-based startup, which has been under the gun to justify its $11 billion valuation, announced last week that it has surpassed 100 million monthly active users. However, the number is “dwarfed by the user bases of some digital contemporaries it competes with for ad dollars,” notes The New York Times, citing Instagram, Twitter, WhatsApp and Facebook. “To live up to its $11 billion valuation, Pinterest must continue to expand its user base beyond 100 million, while proving that it can grow into a robust and viable business.”
