As with any other tool that a computer offers one, Facebook has its appropriate uses.
I keep in touch with good friends on Facebook and they are the only ones who can see my account. As to too much ‘info about me’ being out there... it is already out there whether you use Facebook or not
No doubt the info is out there. I stumbled across my “yearbook” from bootcamp at GLNTC in ‘67 out there on the web. Pictures and all. WTH?
