It has been a while since I looked - the one thing I wanted to fix was the expired link issue. It is rare that I can get past page 2 of the /newest listings before getting the Expired link notification, so, I probably miss quite a few submissions. Basically, the link code that you see is a closure that contains the results for your particular view of the articles. In that snapshot in time, your list remains 'constant' until you refresh it with a few to /newest or / allowing pagination to work consistently as you move through the list. When you get the expired link notification, it means that your closure has been removed due to GC or a server restart. Each time a story is voted on, the global pool is updated, but, until your closure is recreated, you would not see the effect of the vote. Therefore, the shuffling you would see when you or others upvote a story that might change pagination won't affect you. I believe the top 1000 is separate from the normal operation of the site and is run 'at some interval'. I don't recall, but I don't think it is recalculated frequently. Ranking is a function of vote velocity over time. A story that gets a rapid number of upvotes will get pushed up higher than one that has a lot of upvotes, but was submitted hours ago. i.e. 100 votes in the last 20 minutes will be pushed above 140 upvotes in the last 60 minutes. I'm in the middle of some code, but, if I get a chance this weekend, I'll take a look. My lisp is rusty - haven't used it since the late 80s.
