Writing Circle

Has writing come full circle in our technologically advanced world?

Cables used to be only 140 characters, according to Jack Devine, a CIA agent who spoke on C-Span today.
Twitter is only 140 characters.

Email replaces both memos and letters.
This is why many people have different expectations for email. I learned email as a replacement for memos. Other professors seem to have learned it as a replacement for snail mail, which we certainly emphasize in our use of the two terms email and snail mail.

Updated due to a comment on the obtuseness of the post. Sorry about that.
