Privacy and security of personal information has become a big problem in the era of social media platforms. I think nobody can guarantee to keep safe our personal data because hackers are very active and also the companies, governments, many agencies etc are trying to use that data for their own advantages.
Once, Facebook was the most popular social media platform and is still holds this title despite of recent breach of trust. But now people are becoming aware of what Facebook was doing with their personal data and leaving this platform. I was the active user of Facebook and decentralize platform steemit has attracted me a lot. It has plenty of capacity to become one of the most popular social media platform but some certain intrinsic flaws are hampering its progress.
