I agree with all of this, but that does not remove it is still a great tool for keeping in touch when you cannot be together. Should I just go visit all the other friends I have on there instead of keep in touch via FB? I would be travelling non-stop if I did that.
It is not bad, but how often can it reasonably be done? I can open FB for free and see what my sister is up to on a daily basis instead of waiting till I have the time to fly there. And being married to a nurse, a week off at a time is hard to come by these days.
