reddit is widely known for their AMAs. Short for Ask Me Anything, these are reddit posts that invite questions from the community. These questions (or as many of them as possible) are then answered by the poster. Many of the AMAs that receive a lot of attention are hosted by celebrities, but plenty aren’t. To be a good subject, you really just have to be someone who people want to know more about.
All of these link to the main /r/IAmA subreddit, one of the most popular sections of reddit. However, AMAs also occur in niche sections. In fact, for many who want to host an AMA, the best bet for success is to find a subreddit that speaks more directly to what they have to share.
