What We've Lost with Modern Communications

I remember a time in which I would receive actual letters in the mail. Now I get junk mail and some bills. The only time I receive anything of interest through the US postal service is around Christmas or my birthday and when I receive a package from Amazon for something I purchased. Long gone are the days of well-thought out and purposeful letters in which you could build a friendship over words. Time has passed and I have adapted to the modern era as well using texts, 140 characters or less and 6 second Vines to communicate. But is that good?
