NEW YORK (AP) — Trevor Noah, a 31-year-old comedian from South Africa who has contributed to "The Daily Show" a handful of times during the past year, will become Jon Stewart's replacement as host, Comedy Central announced Monday. [...] I may rejoin as a correspondent just to be part of it. On social media, Noah's name became a trending topic within minutes, with some Twitter users saying he not only represented South Africa, but the African continent. "Out of a lot of guys I know in comedy, he probably works the hardest," said Gola, adding that Noah had spent years honing his stand-up routine. Noah, who has appeared on Jay Leno and David Letterman, was the subject of a documentary film by David Paul Meyer, "You Laugh But It's True," which followed his career in post-apartheid South Africa.
