I think one problem is there's no good definition of "social media site". #Section230 refers to "interactive computer service"—that's it. It's never been clear what the limits are.
In '96, intent was really to protect ISPs, webhosts, and AOL-type services with chat/news/boards.
Today, I think drawing a red line when a provider actively promotes certain content for its own benefit (e.g. FB, #YouTube) is a start, as a clear standard.
@kadin User-generated (or submitted) content is a huge element.
There's something of an increasing scale of concern with text, images, audio, video, data, and code / executables, as well.
Algorthmic promotion is another huge element.
What FB and the like bring to bear is both social graph and developing behavioural profiles based on both on-site interactions and off-site activity (online, and increasingly, offline / real-space, including location and commerce data).
