I have tried periodically to abandon Facebook, but I found that hardly anyone would see my blog entries if I didn’t post a link to them from there. At least on my blog, unlike my Facebook page, I can pre-screen and disallow comments. As I said in my reply to the original post, that should be a basic moderation function of any well-designed community site. I like how on Medium comments are not immediately visible unless recommended or responded to by the author, and can also be turned off for individual stories.
