A very interesting article with some pirate history. It makes me think of Phineas Bogg and his past. He told Jeffrey some of his best friends were pirates, and called Blackbeard one of the greatest pirates that ever lived in the episode "Old Hickory and the Pirate."
Maybe Bogg was on his ship and one of the only literate men on board. ;) Smithsonian Magazine usually has some great articles on historical topics, take a voyage to the website and read some!
