So, for example, if you liked videos one, two, three and four, and I like videos one, two, three and five, maybe he liked videos one, two, three and six. Now what's going to happen is, because we like one, two, three at the same time, he's going to be shown four, five, six, and so are we.
Por ejemplo, si a ti te gustaron los vídeos 1, 2, 3 y 4, a mí los vídeos 1, 2, 3 y 5, y a él los videos 1, 2, 3 y 6, lo que va a pasar es lo siguiente: dado que a todos nos gustan 1, 2, y 3, a él le va a mostrar 4, 5, 6, y a nosotros también.
