Why is "Internet metaphors" trending?

Wikipedia Overview

Internet metaphors provide users and researchers of the Internet a structure for understanding and communicating its various functions, uses, and experiences. An advantage of employing metaphors is that they permit individuals to visualize an abstract concept or phenomenon with which they have limited experience by comparing it with a concrete, well-understood concept such as physical movement through space. Metaphors to describe the Internet have been utilized since its creation and developed out of the need for the Internet to be understood by everyone when the goals and parameters of the Internet were still unclear. Metaphors helped to overcome the problems of the invisibility and intangibility of the Internet's infrastructure and to fill linguistic gaps where no literal expressions existed.
