Sean L. McCarthy has written about comedy for the New York Daily News, Entertainment Weekly, the Boston Herald and other publications. Before that, he also worked as a professional stand-up and improv comedian, opening for many comedians you know and some you don't know but should.
He won New York's Funniest Reporter, judged by the folks from mediabistro and gawker, which means it got blogged here. Gothamist also interviewed him, and you can find that here.
Most importantly, though, you can read all of his round-the-clock reports about comedy on The Comic's Comic.
