Marine analogies for Google and Facebook

We were sitting around the office talking about the difference in the ways Google gets information from the way Facebook does. I figure Google is like a shark.

Always swimming, always gathering up information, constantly patrolling.

Facebook waits for you to come to it. Positions itself accordingly. Facebook is an angler fish.

But instead of a light on its head, it holds up your classmate from third grade and lets you swim on up. See? Now you understand.
