Oh no, I lost that karma way before I whined about it. I knew as soon as I posted that it's just a karma burning exercise. Any contrary (or slightly contrary) post in a discussion about Apple is pretty much treated like leprosy. I know that going in. I was just observing that the algorithm appears to have changed and now downvotes are all counted regardless of what the displayed score is.
You didn't lose all of it before you whined. I know that because I downvoted your whine about being downvoted, and didn't downvote your bah-it's-just-a-netbook comments.
(I have a policy of always downvoting whines about being downvoted and "I know I'll be downvoted for this ..." comments and so forth, because (1) they're boring and (2) I have a nasty suspicion that they produce net-positive results for their authors and want to make them not do so.)
