Mark Zuckerberg did just fine in his first turn in the Congressional hot seat. He was confident. He capably tackled queries about his business's lucrative ways. The 33-year-old billionaire appeared humble throughout much of the hearing, with only a few smug smiles.

The best news for Facebook the company was that Zuckerberg ably deflected any challenges to the beating heart of its economic model: its hungry data collection and the fine-tuned targeted advertising based on that data. Zuckerberg's success is a win for anyone primarily concerned with the company's market value. But it's a loss for the rest of us.
