In a first for an American president -- and perhaps any president in the world -- Barack Obama hosted an IAMA ("I am a") discussion on social news site Reddit. The President took questions on the site over the course of about half an hour starting this afternoon at 4:30 pm EST. News spread quickly of Obama's appearance on the site, and the resulting traffic caused the page hosting the discussion to be unavailable multiple times over the course of the IAMA.
