Depends on how time travel works and how the choices work.  Maybe you're creating a new, better universe that exists independently of the old one.  Maybe the new one replaces the old.  Maybe you're just making sure you can get to the universe where the "right" option happens.  Maybe time travel is one of the choices…

I figured that several of the Enterprises had embarked on this plan at about the same time, and that was basically the quantum waveforms collapsing.

And another universe where the Mmrnmhrm and the Chenjesu merged more perfectly.

I actually quite enjoy the "niceness" - which I just see as, y'know, professional people who respect each other working together on important issues.

I don't think it's "useless" so much as "something that people think has to do with how good a story is, but is pretty much independent of quality".

The thing is, 2001 wasn't ponderous.  It was filled with tension in every nook and cranny until HAL dies, at which point the tension is replaced by wonder.

Not even Cookie Monster!?

Oooooooh.  This is a downright neat idea.

Obviously, it was the presence of Gary Seven that prevented the Eugenics Wars.

Huh. I found it funny as all heck. Oh, well, different strokes.

Reading about why someone doesn't like something can be fun.

I thought it was more that Star Wars came out, science fiction movies became popular, and they figured a movie would make more money than a TV season.

Hm, so the downfall of Oliver Cromwell was caused by semicolons…

Definitely not the *only* worthwhile Star Trek book, not while "How Much For Just The Planet?" still exists.

Man, after I figured out how to use semicolons correctly, I got seriously addicted.

This - it's less the length of the post-Sauron bits, and more the way they're presented.

There was the anti-Jellico-because-he-is-a-dick faction, the pro-Jellico-for-the-reason-above faction, and the anti-Jellico-because-his-dickery-was-completely-wrong-for-the-situation faction. (Not that I'm agreeing with the last faction - I haven't seen the episodes yet! - but that's how I saw the opinions fall.)

Personally?  I always liked the "scanning for lifeforms" song.

…so, people who like to think about anthropomorphic animals having sex shouldn't have anything to do with comics where anthropomorphic animals are having sex?

Generally, I agree, but I don't think Ra's fits the stereotype mold.  He's clearly on a different level than, say, the people letting the rage virus monkeys out in 28 Days Later.
