What does it mean do be a Sal?

Nice little post over at the NY Times City Blog, about the pride in the name Sal, Salvatore and Salvador. The post was spurred by the recent naming of Carroll Garden's own Sal Cassano as the newest FDNY Commissioner. Local pizzeria owner Giovanni Esposito commented on the name:

"[Mr. Esposito] is called John but is both the father and son of Sals, said he felt a slight thrill upon learning of Mr. Cassano’s accomplishment on the 11 o’clock news.

“I felt kind of proud, because he’s an Italian-American, and my father was named Salvatore,” Mr. Esposito said. “You know, I felt good about it inside.”"

Stay proud, cugino.
