But while we're learning what we're eating or where we're flying, we haven't been able to use Twitter to determine how we're feeling. Researchers at Harvard and Northwestern have created a video that shows the mood in the US, as inferred using over 300 million tweets, over the course of the day. The results? The early morning and late evening appear to provide the highest levels of happiness. Geographically, the data points to a significantly happier west coast, which is consistently three hours behind the east coast."
The computer can't tell you the emotional story. It can give you the exact
mathematical design, but what's missing is the eyebrows.
