I assure you social media existed well before Twitter. Twitter's original niche was called "microblogging", which was novel at the time. It did solve a problem of a lot of fractured discussion and how certain types of discussion would take place and be visible. It also had the feature that celebrities might respond to you. It was a way to get news directly from journalists. It had its network effect and took off.
