FB is such a prolific social media platform, just have to tweak some settings. With FB, I just unfollow those friends, then it does not show on my news feed, so I do not get to read all their posts..whether inane or interesting. Pretty much I unfollow all
but still keep them in my friend's list. There are some instances you just want to share empathy to what they are going through, like bereavement, or job loss, gross weather conditions or their simple joys like bdays, weddings, travel etc.
Pretty much like reading a newspaper, and I just read the part I like, that's how I handle it, if I want to read their page, then I go to their page. If I don't, then I leave them alone and just concentrate on my own postings. I also block people who are too obnoxious or just too undisciplined in posting replies, that way they will not find me or I put them in restricted category so they cannot see my postings. And I also reject being added as their friend..after all, it is my page.
