1. Their users don't trust them.
2. Advertisers like GM don't believe their advertising platform works.
3. They don't understand mobile.
4. Their crack design/engineering team is too feeble to design a simple photo APP like Instagram.
5. Their shareholders are dying to sell out in the IPO.
6. The valuation is hyperfrothy.
