Ryan it is the overarching brand beneath which fall the Silicon Alley Insider (launched May 16, 2007) and Clusterstock (launched March 20, 2008) verticals.^{[clarification needed]} The site provides and analyzes business news and acts as an aggregator of top news stories from around the web, each with an "edgy" commentary. Its original works are sometimes cited by other, larger, publications such as The New York Times and domestic news outlets like National Public Radio. The online newsroom currently employs a staff of 45, and the site reported a profit for the first time ever in the 4th quarter of 2010.

Neil deGrasse Tyson ( /ˈniːəl dəˈɡræs ˈtaɪsən/ born October 5, 1958) is an American astrophysicist and science communicator. He is currently the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space, and a research associate in the department of astrophysics at the American Museum of Natural History. Since 2006 he has hosted the educational science television show NOVA scienceNOW on PBS, and has been a frequent guest on The Daily Show, The Colbert Report, Real Time with Bill Maher, and Jeopardy!. It was announced on August 5, 2011, that Tyson will be hosting a new sequel to Carl Sagan's Cosmos: A Personal Voyage television series.

Tyson was born as the second of three children in the borough of Manhattan in New York City, but was raised in the Bronx. His mother, Sunchita Feliciano Tyson, was a gerontologist and his father, Cyril deGrasse Tyson, was a sociologist, human resource commissioner for the New York City mayor, John Lindsay, and was the first Director of HARYOU. Tyson attended the Bronx High School of Science (1972–1976, astrophysics emphasis) where he was captain of the wrestling team and was editor-in-chief of the school's Physical Science Journal. Tyson had an abiding interest in astronomy from the age of eleven, following his visit to the Hayden Planetarium at age nine. Tyson recalls that "so strong was that imprint [of the night sky] that I'm certain that I had no choice in the matter, that in fact, the universe called me." He obsessively studied astronomy in his teens, and eventually even gained some fame in the astronomy community by giving lectures on the subject at the age of fifteen.

Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known as one of four co-founders of the social networking site Facebook, of which he is chairman and chief executive.

Zuckerberg was born and raised in a Jewish household in New York state. While still in middle school in his early teens, he took up writing software programs as a hobby, beginning with BASIC, with help from his father. His father then hired a tutor to help his son develop his programming skills further. Zuckerberg's enjoyment in writing programs led him to developing computer games, writing a music player, and setting up a primitive home network he called "ZuckNet." His private tutor calls him a "prodigy." In high school he excelled in classic literature and science, while becoming proficient in four other languages. He was also captain of the school's fencing team.

He later enrolled in Harvard, majoring in computer science and sociology. In his sophomore year he wrote a program called Facemash as a "fun" project, letting students on the college's network vote on other students' photo attractiveness. It was shut down within days, but would become a template for his writing Facebook, a program he launched from his dormitory room. With the help of friends, including roommate Dustin Moskovitz, Facebook went national on other campuses, and they moved to Palo Alto, California. By 2010, the site had an estimated 500 million users worldwide. Zuckerberg and Facebook have since been involved in various legal disputes initiated by others who have claimed a share of the company's profits due to their help in setting it up. Zuckerberg is the largest individual shareholder with 28.4 percent of the common stock and controls 56.9 percent of the voting power. As of 2012^[update], his personal wealth was estimated at more than $19.1 billion, making him one of the world's youngest billionaires. Zuckerberg is one of the 30 richest people on Earth.
