I don't particularly care for the drama and the trivial stuff some folks complain about, though I admit I've done that occasionally. I also don't like self-centered posters and attention whores who have to announce every single thing they do, e.g., "Hey, look at me eating this ginormous cheesecake!" That's when I use the Unfollow or Unsubscribe option.
As far as posting my own updates, I put my contacts in different user groups so that I don't have to "broadcast" said updates to everyone on my list. That way, family pictures stay within the family and close friends, work rants are none of other people's business, and so forth.
