I am the founder of Sporcle, AMA!
My short bio: Howdy. My name is Matt Ramme, and I created Sporcle back in 2007 to help me do better at crosswords and Jeopardy. The games on the site have been played now over a billion times and we also run nearly 200 live trivia shows in a few U.S. cities.
Edited to add: We do have a small presence here on reddit: r/sporcle
