You know the ones who go away and give you a blow by blown account every day on what they are doing, where they are eating etc, sometimes multiple times a day.
Are friends expected to read it all and like every single post?
What happened to privacy, what happened to telling people about it when you get home?
Not against it totally, but several times a day, what's wrong with them?
They seem unable to enjoy a holiday without broadcasting every single thing. It's horrible the way FB has got to some people!!
