In the past with only access to written text people were forced to letters or books communication was slow.  Now however with things like twitter and facebook people can have entire conversations over vast distances that would have taken months of back and forth letters now instantly.  As well because of how slow letters were you had to really say something anytime you sent one and now you could simply send your friend a message just to say “hey”.  As well the internet makes it much easier to get more important texts out in the public.
