r/IAmA

r/IAmA (or /r/IAmA) is a subreddit on the social news aggregation and discussion website Reddit. The name is an abbreviation of "I Am A" and refers to a specific type of post format. In an "IAmA" post, the poster identifies themselves, usually with some context indicating their expertise, experience, or notable characteristics, and invites other Reddit users to ask them questions. The poster then attempts to answer these questions in the comment section.

The subreddit hosts a wide variety of IAmAs, ranging from everyday individuals to celebrities, experts in specific fields, and people who have experienced unusual or notable events. The purpose of r/IAmA is to facilitate open discussion and knowledge sharing between the poster and the Reddit community. The quality and accuracy of the answers provided depend entirely on the poster, although community moderation and downvoting can help to highlight inaccurate or misleading information.

Notable IAmAs have included those with Barack Obama, Bill Gates, and numerous other public figures. The subreddit also features a verification process to confirm the identity of the poster, particularly for those claiming to be well-known individuals or experts.
