My issue isn't learning it, haven't bothered. My issue is FB like so many others sell too much info and lose it as well. I do know people who use it all the time and post where they are what they are doing and so on. I'm of the my business is nobodies business when I'm not home, what I have, where I frequent and so on. All to many sites are hacked etc. I was one of the huge group of people with a T/S clearance who's info was stolen in a hack. I was under understanding the US gov would keep my info safe but they didn't so I don't hold out on to any thinking that sites like FB are safe. All they do when they lose everything is give you free monitoring for a few years. What a joke thats been, nightmare actually. Hell even Zukerberg won't offer up info they expect others to use on those sites. Nope, Less is more ....But for those that have never been burned and are comfortable with it enjoy, Im sure its a lot of fun. I totally get it, Till it gets you and hopefully it never will.
