Ever wondered what the life of a World War 2 nurse was like? Or an Uber Driver? A Syrian refugee? A police dispatcher? An employee at an ostrich ranch? Here at /r/IAmA, you can ask them yourselves!

The name itself is suggestive to what the sub is about – “I Am A”. The person in question opens a thread introducing their specific situation, whether it be their profession, their role in a famous event, movie, scientific discovery, etc., or even an unique health issue. Then, Reddit users ask questions on the thread, and the person answers it – a live Q & A over Reddit! The threads you see are the live questions are responses, typically over the course of several hours. However, if you want to ask questions yourself, check the sidebar and find the time and date for the next scheduled AMA (Ask Me Anything), and show up!

Not interested in unique people? The sub also features many AMA’s by scientists in prominent newsworthy researches, such as NASA Mars scientists, the NASA New Horizons team, astronauts on the ISS, engineers of the Mars Curiosity rover mission, the people at the Large Hadron Collider, among others – so you can have fun while learning science and world news!

Still not interested? /r/IAmA has also welcomed its fair share of celebrities in the past. Among the highest voted threads are the AMA’s of: Barack Obama, Gordon Ramsay, Patrick Stewart, Bill Gates, Elon Musk, Edward Snowden, Bernie Sanders, Peter Dinklage, Neil deGrasse Tyson, Bill Nye, Buzz Aldrin, Bill Murray, Ian McKellen, Arnold Schwarzenegger, Keanu Reeves, Harrison Ford, Chris Pratt, Daniel Radcliffe,  and Sean Bean, among others./r/IAmA is a chance for users to see their celebrities online (one of the strangest online communities, as well), and get to know them outside of their profession.

So, hop on to /r/IAmA, a sub that exemplifies Reddit’s function as a platform for exchanging knowledge, and learning from others’ experience. Read, and learn!
