Big Data Could Cripple Facebook

So there's this startup called SmogFarm, which does big-data sentiment analysis, "pulse of the planet" stuff. I spotted them last year, and now they've got an actual product with an actual business model up and running in private beta: KredStreet, "The Social Stock Trader Rankings," which performs sentiment analysis on StockTwits data and a sampling of the Twitter firehose to determine traders' overall bullish/bearish feeling. They also compare reality against past sentiment to score and rank traders based on their accuracy, which is more interesting. It's a first iteration, but it looks pretty nifty, and I like the idea of a ranking system wherein unknowns can leave high-profile loudmouths in their dust by virtue of simply being right more often. Even if I feel slightly uneasy when I imagine such a system being applied to, say, tech bloggers. Actually being held accountable for what I've written in the past? Doesn't that just seem terribly wrong?
