I love Titor, whether or not he is genuine does nothing to discount the wonderful story of the whole thing. If he was a hoax he did the one thing no one else ever does, he had pictures and schematics!
Now, I wasn't involved in the Titor discussions at the time but from what I remember from reading the transcripts I don't think he really had all that much vested in predicting the future for us. He was here to get his computer components and go back home. In fact, I bet he gets the whole "tell me the future" deal every time he comes back.
I've also always thought his divergence theory was interesting and actually in line with current multi-dimensional theory.
There is also the fact that some scientists say that we've either been visited by time travelers or time travel is impossible, I guess it comes down to which you believe.
I don't really think it takes that much of a stretch of imagination to consider time travel a reality, at least this divergence theory travel. Perhaps, if everything had lined up right, a scientist's experiment had one extra electron, we could have a working time machine similar to Titor's right now.
Of course, it is late and I'm here leisurely



, albeit a prudently skeptic one. titorite explained it well.
