flooding the earth with light

since the point was brought up about light, and what kind of light you might be, it made me think of this talk. i think maybe the light is not the problem but as was said a light on a hill instead of under a bushel. maybe the question is not only what kind of light are you, but where are you placing it, what are you doing with it? in this talk, elder bednar invites us to flood the internet with the gospel. how can you do that? what can your little personal flood be?
