One thing I dislike about the 'average karma' is that it discourages engaging in an extended discussion. For example, if you reply to this post, you may get a number of upvotes, but probably not as many as your original post. This creates an incentive just to ignore replies (when possible) so as not to bring down your average comment score.
Done. :P
This algorithmic craze is too clever for its own good. It is particularly evident in the false-positive bans.
(And I swear, it's scary how HN joke comments are indistinguishable from the real ones.)
But you're correct in that the current algorithm (or any sufficiently transparent algorithm) does lend itself to gaming. It might be harder to game if you didn't mind penalizing comments based on the quality[1] of replies they generate, then sorting based on the thread's average quality would mean that there's less incentive to post in the top thread just to get exposure, since your new, karma-less post will drag down its average and subsequently could drag down the thread. That could get prohibitively expensive to calculate for huge threads, but would be less prone to gaming, I think.
[1] If we can hand-wave "karma" to mean "quality"; I get way more upvotes when I am flippant but technically correct than I do when I try to be thoughtful.
Locally perturbing and simulated annealing sound interesting. Maybe we could convince pg to reticulate the splines as well.

Edit: Why am I being downvoted????
It's not like I'm a menace to the community.
I assume the goal is to encourage high-quality discussions (including extended discussions/back-and-forth), in which case average comment score will work against that.
I never would have guessed.
I wonder if this thread could be turned into a parody of the parody?

Crisis averted.
As a tool or "quality score" that aims to control and keep a forum from derailing this kind of a scoring system has probably done OK. Not sure if it is solely responsible for these effects on sites like HN and SO, but there's not denying that the signal to noise ratio is far better than for example USENET S/N or some forums out there (vBulletin or phpBB type).
Having operated a forum before I can tell you that it can be an absolute nightmare (I was using vBulletin) on many fronts. HN seems to be able to maintain decent quality.

Didn't realize until stalking through to the author's commentary on his personal blog: http://bradconte.com/hacker-news-parody-thread.html, because the relevant replies (including the author's own: ctrl+f "B-Con") were too far down this thread to ever see without foreknowledge.
But now its time to be very HN about it.
> Rats, top comments will be impossible to beat.
Actually I think I have a solution to this, though its just guesswork.
I'm not particularly well known here (or anywhere), but either people actually like the words I say, or I simply have yet to make a complete ass out of myself. (I think one of these is more plausible, but who is to say.)
My average karma on HN is 20.59, which seems to be a lot. Specifically, on the Leaderboard[1] that puts me in fourth place among the HN big names for average karma (though I have nowhere near the total karma to appear there).
I've noticed that when I reply to a post, even if there's already 30 comments, my post usually ends up at the top. And it stays there, even if no one replies, and even if I don't get many or any upvotes for it, for a few hours sometimes.
Alas I don't know for certain, but my guess is that if you have a high average karma then your posts are automatically weighted higher, so you can inject your opinion into almost any topic at any time. This affords me the luxury of being a contradictory whine even if I come late to the party!
Can anyone confirm or deny my suspicion here?
