Remember when Twitter first became popular? It was a place where folks shared random thoughts about their day or even just the undirected trajectory of their introspection.

But now, ten years later, the social media website has become the main source for breaking news, it’s become a platform for celebrities to shut down rumors, it’s become a place for humanitarians and advocacy groups to share a story and it’s also a place for politicians to share their agendas.
