President Obama stole Internet attention from the Republican National Convention on Wednesday by conducting an Ask Me Anything (AMA) session on Reddit.

Reddit is a wildly popular social media community, in which users share links and comments. In an AMA session, one person fields questions from the community. A variety of noteworthy people have taken part in these sessions, including Steve Colbert, Jimmy Kimmel, and “Jeopardy” champion Ken Jennings.

Around 4 p.m. ET, Obama tweeted that he would be taking questions online starting at 4:30. White House Press Secretary Jay Carney even tweeted a photo of the president sitting in front of computer, presumably scanning the questions. Shortly after the session began, however, users began complaining that they couldn't access the site because of the high volume of activity.
