Danielsangeo is the pseudonym of a Wikipedia editor of a few pages. Hailing from Seattle, Washington, his interests are atheism, liberalism, and others. The pseudonym originates from when when he created his first user account back in 1994 when he had to make up a pseudonym. The Karate Kid was on television and, since the main character shared a first name with him, he chose "DanielSan" as his pseudonym. Later, he would get an account on GeoCities, which would later be bought by Yahoo!, which he then changed his pseudonym to Danielsangeo in order to reflect his dismay at the acquisition. The pseudonym stuck. He's still known as "DanielSan" in many circles, though.
