Less Wrong is still under construction. Please post any bugs or issues with Less Wrong to this thread. Try to keep each comment thread a clean discussion of each bug or issue.
Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
Meh. You said yourself that someone behaving irrationally has unpredictable behavior. So downvotes for stupid reasons are just noise, and should in large numbers be countered by either upvotes for stupid reasons, or other comments' downvotes for stupid reasons. If there is still a considerable amount of voting for good reasons, it should usually show through the noise.
This analysis obviously assumes that there isn't a systemic bias in the mix, like "always upvote Eliezer" or "always downvote Marshall".
"You said yourself that someone behaving irrationally has unpredictable behavior."
No, I didn't. Someone can be irrational, yet completely predictable and consistent. Go back and re-read what I said - you haven't understood it.
"This analysis obviously assumes that there isn't a systemic bias in the mix"
We're dealing with human beings. There are ALWAYS systemic biases involved.
