I tend to vote such threads to around a couple of karma myself. 0 isn't unreasonable. < 0 is quite peculiar. But my confusion was resolved in this instance. Someone messaged me and explained that he was trying to work out why the votes were fluctuating so much (4 -> 0 in an hour) so was testing what would happen if he put down one more to -1.
As a side effect to these posts going up and down I've now started paying attention to only the last digit of the score. The 10s are mostly noise!
A monthly thread for posting rationality-related quotes you've seen recently (or had stored in your quotesfile for ages).
ETA: It would seem that rationality quotes are no longer desired. After several days this thread stands voted into the negatives. Wolud whoever chose to to downvote this below 0 would care to express their disapproval of the regular quotes tradition more explicitly? Or perhaps they may like to browse around for some alternative posts that they could downvote instead of this one? Or, since we're in the business of quotation, they could "come on if they think they're hard enough!"
