Facebook is a terrible social media site. It is so bad that I had to leave due to the censorship, authoritarian controls and blocking the vast majority of my friends from seeing my posts unless I pay. It takes the creative capacity of people like you and I and capitalizes on that for profit, control, surveillance and intelligence gathering. Sure there are lots of people on it, but it does not match my definition of what a good social media site should look like.
It is so bad that when I came here, I got more traffic and interactions with 100 followers than I did with over 2000 on facebook. That is sad indeed.
