I used to love TED Talks, and would watch each one religiously as it was posted. With the spread of TedX, though, and regional conferences posting every one of their speakers’ talks, the quality has diminished to the point where I don’t bother clicking, because I don’t want to spend 5 minutes determining if this is a future classic or a total waste of time.
This talk by Roman Mars, though, is definitely the former. Engagingly presented (I want his podcast as a video!), funny and informative. Infotainment is a pejorative term but it should be applied without implied snark here. 18 minutes that fly by and are worthy of a rewatch.
