Sebastian Wernicke finds the formula for good TED talks.
Sebastian Wernicke gives a wonderful TED talk on constructing TED talks. He looked at all available TED talks with their popularity, and he was able to extract certain elements that made each talk either popular or unpopular. These factors might be the particular words used, the color of the slides, or what the speaker wore.
From his analysis, he was able to create a formula for the perfect (or worst) TED talk. Although he's doing it as a bit of a goof, he actually makes some good points that people might consider about making their talks.
There's still time before the summer conference season to use his suggestions for your own talks.
