Reddit reviews Conviction of a Time Traveler

Have you heard of John Titor? If I remember right, someone was posting on physics message boards back around 2002-2003-ish claiming to be from a future America after Civil War II, stated he came from Gainesville, which people were calling Fort UF. Some would press him for info about his timeline, others would press him for proof/explanation on time travel. As I recall, some of the things he said weren't known at the time but some has been verified since. He's considered one of the greatest hoaxes of our time, assuming he's a hoax. The original book on the matter was a limited print run by a small publisher, copies going for hundreds of dollars now, but there is also this book now that I've been meaning to pick up. https://www.amazon.com/Conviction-Time-Traveler/dp/1453643184/
