I stopped using Facebook years ago and I could not recommend it more. I found it to be mental pollution at best and and a total waste of time. If you want to 'keep in touch' with people, call or text them. Make an effort to actually interact with the people who matter to you.
> call or text them There is no difference between a call or text and a message on FB, the medium doesn't change the context.
Maybe it's because it personally takes me more effort to make a phone call, or the added tone of voice, or maybe it's just the instant dialogue that the call creates. Calls will always be more special to me than a facebook message. Just as a handwritten birthday letter in the mail is more special than the same message in a text.
