"Charlie" and "Al" change western grammar

In the 8th century, the literate began to use uppercase letters in their writing. According to business writing expert Stephen Wilburs, the change can be traced to Charlemagne (Charlie) and Flaccus Albinus Alcuinus (Al) as a means to make reading easier.

In addition to his humorous history lesson, Wilbur offers a guideline on capitalization in English.
