I visit a few online forums, MFK being one among them, that serve as excellent sources of information relating to various interests I have, as well as being convenient repositories or "libraries" for that information. Even so, there is much in them that is so completely useless and wasteful of time, such as most "Off-topic threads"
, that I am always hovering on the verge of dropping them altogether. And these forums represent the "best" type of social media, IMHO.
But Twitter, Facebook, etc.? Not a chance...and I don't care who is running them. They are a constant reminder to me of the ongoing devolution of Homo sapiens as an intelligent species; and I already see enough evidence of that in day to day life, without seeking it out on the internet.
Censorship is generally not a good thing...but it is not always an altogether bad thing either. There are plenty of people who have nothing to say that is worth listening to, and whose only contributions to intelligent debate are those brief periods when they actually shut up. And don't even get me started on the trolls who actively seek to start arguments by posting inflammatory drivel...
