I like the idea of this, but having so many integral services in one silo scares me a bit. Recent security disclosures by FB, etc. also make breaches feel more like an inevitability, not just a possibility.
How do you plan to hold yourselves accountable in the event of a massive data breach? Everyone seems to take security "very seriously" after they're forced to make a disclosure, but few companies make concrete assertions regarding security before a breach.
