What I mean by that is that it passively observes people as they live their lives. It scans the world's blogs and looks at what people are writing, and these people don't know they're being watched or interviewed.
Lo que quiero decir es que observa a la gente de manera pasiva a medida que viven sus vidas. Escanea los blogs del mundo y observa lo que la gente está escribiendo, y esta gente no sabe que está siendo observada o entrevistada.
