Where was I?
In one sense, I was on Mars...in the sense of my lost train of thought, I think it's too late to come back. That was an interesting contribution, though. I found myself getting wrapped up in following links to various references to AH...and I think there's a good analogy between the pitfalls of getting lost following the branching of hypertext and getting lost trying to follow the branchings of time!
"Probability Broach" looks interesting, despite what appears to be a big axe to grind to portray a libertarian utopia. "President Ayn Rand"?!! "Admiral Heinlein"?!?! Could be a hoot, and perhaps interesting too. I'll keep an eye out for it.
