Facebook started cribbing from Twitter in recent years with the introduction of unfollowing. In short, this means that you can filter out posts from some of your most irksome of friends - the 'loving life' updaters are usually first for the cull - without resorting to deleting these well-meaning irritants. If they conducted a poll on this, the good money is on everyone claiming to have at least a couple of peeps on their unfollow list.
