The distinction I was going for was things that predate the classification terminology. I guess there's no particular reason not to apply such classification retroactively, but it feels a bit weird considering that in the heyday of these technologies, few if any people referred to them as social media. Seems a bit like saying "let's stream some music" as you're loading up a CD player. Technically yes there is a stream of bits but it just seems silly to speak in such terms.
