He's best known for producing renowned documentaries such as Cocaine Cowboys and The U, but homegrown filmmaker and provocateur Billy Corben is also a serious newshound with a startlingly effective Twitter presence. Corben has more than 35,000 followers, and his feed serves as its own Miami-centric internet force — funny or strange aggregations of shark attacks, bikini-clad grandmas getting arrested and other Florida insanity, hard-hitting engagement with Miami-Dade politicians over police misconduct or local corruption, plus sharp commentary on everything from University of Miami sports to civil rights. In other words, if it's important to Miami, Corben is probably tweeting about it. (In fact, he even made some judicial South Florida history by inspiring a defense attorney to request a mistrial after Corben had tweeted during jury duty; the verdict stood, and Twitter rejoiced.) His feed is so prolific it's a wonder Corben has time to do anything else.
