Yes. Personally, I would keep it to close friends, family, professional. I would avoid FB pages that are of a social nature where people have a common hobby interest or pursuit; they can be particularly bitchy places.
As just mentioned: NEVER air your dirty laundry on FB; it will be recorded forever for posterity; 'juicy' stuff gets shared and it's out of your control once that happens.
I personally think it's a sh-hole but my "friend" base was too wide in retrospect; I was in the angling fraternity and the nature of my position meant I had to be open to everyone, which is now history.
