No, that was just something he was trying to get out of his system.

You got that right. After this thing becomes relevant in the story, there may be complains, and while I'm sure Eliezer will explain it competently, people are prone to throwing accusations of asspull around. So if there is enough detail in a time-logged, non-edited comment, it can be pointed out later. 'It's not an asspull, look, this idiot even guessed it. You can read about the stuff he used to do it in the Sequences.'

Now that I no longer feel like I'm doing LW a disservice by sitting on such validation, I can go back to speculating quietly.

As for the rest, I guess you're right, though I note that's not why you started this thread. Also of note is the fact that this is LessWrong, not some random ff site. Getting things right might be higher priority here, than elsewhere.
