The letter has it all.

In a letter writing, one can easily sense a personality by hand writing and the way a person writes the alphabets. Can easily trace out few traits through handwriting. Now with the advent of mail, everything has turned into a standard.  Everyone's text turned out to be formal, simple.  Further came the fonts to set out the context of the text. But still, can't make out the other's personality through the text, especially in the mail. The medium has got a lot of influence on the way we think.

This reminds me of the lines from the book. The Shallows: How the Internet Is Changing the Way We Think, We remember. 

"As our window onto the world, and onto ourselves, a popular medium molds what we see and how we see it and eventually if we  use it enough, it changes who we are, as individuals and as a society."
