There has been criticism about the privacy of social media. The likes of Facebook and Twitter, but I don’t think they’re the problem. There are privacy issues, but you can configure these applications not to share information. We should regard the internet as a public space and not put anything accessible to it you regard as private. The best thing about the internet is it provides a global means of communication, sharing. It broadens our connections.
Blockchain will secure it better, if used you won’t be able to remain anonymous anymore. I think the complaints about social media are misplaced, it’s just a place to meet, like any public place, a coffee shop. You can be influenced anywhere if you’re given to persuasion. Importantly, maintain you individualism.
