Ask PG/RTM: How are you dealing with hn point inflation?

I'm sorry for the meta-question about the workings of the site, but I've been curious about the issue of point inflation on HN for a long time. These days, it's not too uncommon to see a story with over a thousand points, and stories with over 500 points seem to be an everyday occurrence. I'm not the best or most prolific commenter, but when I do post, I've also noticed inflation in the points awarded to my comments. I might be nice most of the time, but seriously, I'm no where near as good as my score seems to indicate. For example, I know %5 of my score is due to one of my friends dying and I let people on hn know because some may have known and worked with him. That feels both weird and wrong, but there was no way to make a "no-points" post without the doubts caused by using a throw-away acct. Anyhow, that's another matter. I'm not obsessed with points, in fact, I really don't care and often spend weeks not even bothering to log into hn. The only reason why the points are interesting is they are used in your sorting algorithms. It's very apparent your sorting algorithm is more complex than the roughly stated "points over the square of time since posted," so I've been wondering how the heck you are managing the point inflation problem? If you don't want to answer because it might enable people to game the system, I'd totally understand, but I am extremely curious how the hell you're able to manage the inflation so well. If there's any way you can explain it without killing the golden goose, please kick the knowledge downstairs to the unwashed. Thanks!
