What do Mary Shelley’s Frankenstein, Wilfred Owen’s “Dulce Et Decorum Est,” H.G. Wells’s The Time Machine (and The Days of the Comet, and The Island of Dr. Moreau, and Conrad’s Heart of Darkness), the Danse Macabre, 1984, punk music (The Clash!), Twitter, Wikipedia, The Wisdom of Crowds, The Starfish and the Spider, DIY, Internet piracy, and podcasting have in common?

It’s a question for my British Lit.
What I mean is, what is one thing that connects them all? It can be simple or complicated.
Think like a web outline or something.
Ex) Monsters connect Island Of Dr Mouro and Frakenstein.

But it needs to be something to connenct all of these things.
