Time Traveller or crackpot, you decide!

What are your opinions about John Titor? For those of you who don’t know (I never knew about him until today) in November of 2000 a man with the user name Timetraveler_0, calling himself John Titor, joined a chat and told people that he was a time traveler from the year 2036, he gave very detailed and somewhat convincing information about the future, the structure of the universe, and his methods of time travel for 5 months at which point he said he had to return to his original time.

Here is a site that contains many of the questions that people asked him and his answers. It is very interesting.
