I appreciate that you have your own opinion and you simply don't agree with me. It's totally fine. I in fact talked about this in the blog that it is very much possible that you will not agree with me. I personally find a lot of social media to be a waste of time for those who don't make use of it, such as you mentioned, for businesses.
Yes there are good sides of social media and many have actually turned their life around. But for every life turned there is maybe 10 lives which have halted I think.
