Besser als Michael Sippey kann man kaum sagen, was Social Media Literacy ist:

In short, "media literacy" was focused on creating smarter media consumers; understanding how media’s produced and distributed, the biases behind it, etc. (See also deconstructionism, etc.) "Social media literacy," on the other hand, needs to be focused on creating smarter media producers, who understand the ramifications of a hyper-connected zero-cost-of-distribution world.
