Media was always already social. If I email my friend a link to a YouTube video, is the Internet a social network? I think what we think of when we think of 'social media' or a 'social network' is an integrated platform that lubricates particular potentials, like being able to create and share content with friends and fans. But there are other ways to realise those potentials, including ones that require the interfacing of different platforms (or media, in the McLuhanian sense), or what might be perceived as different platforms at one scale, and the same platform at another scale, as per my Internet example. And, the multiplicity of platforms, and the interfacing between them, might confer additional advantages and open up yet more potentials.
