I think social media is more powerful than ever and you can look at last general elections in India, political parties hired hundreds of social media campaigners to improve their vote count and for run up to the next general elections political parties and politicians are using more and more social media tools to spread fake news and propaganda to influence votes. Tragedy is that 95% information on social media is not correct and majority of people around 95% dont even bother to check the accuracy of the information and share with others without knowing the actual impact , social media is doing more bad than good for general public.
