This following was originally sourced by Bits Blog at New York Times. People are concerned that Slingshot is basically a Snapchat clone, a fair assertion. But I love the analogy used to describe technology clones in general.
"Did you know there are over 150 varieties of Finches? Each slightly different, maybe color difference or a larger beak or bigger wingspan. They came about by iterating on the Finches that came before,” the user wrote. “In fact, that’s how most advancements come about in nature, poetry, art, and yes, even technology. We take what came before and iterate on it."
Not all clones, despite the terminology, are created equal. Personally I prefer innovation by iteration and when a clone does something similar but better, I tend to commend developers. There are no original ideas, there are only better ideas.
