Facebook Friend or Foe??

Well this has to be the third argument my husband and I have gotten into about this subject. He saysit has people on there that are just looking to cause trouble and to find out where you are. But in my defense I am only on it to see old friends, their families and to actually be in touch with a few really good people and some family members that I have not seen or talked to in years. My cousin Steph and I have not seen each other in about 20 some years. I always thought of her but you know how it goes you hear this or that or you just get caught up in life! Well she friend requested me and oh my gosh, she is all grown up. LOL!! So what are your thoughts on facebook?? I already know my thoughts and my husband's thoughts!! But I don't know your thoughts on facebook!!!
