Thanks - lots of handy links, including one [http://www.seomoz.org/blog/reddit-stumbleupon-delicious-and-...] to "Reddit, Stumbleupon, Del.icio.us and Hacker News Algorithms Exposed!"

The formula for HN (as of July '08): (p - 1) / (t + 2)^1.5 where: p = votes (points) from users. t = time since submission in hours.

p is subtracted by 1 to negate submitters vote. age factor is (time since submission in hours plus two) to the power of 1.5.

Thanks for the comment, kakooljay. That was one of my favorite links that I found in writing the article as well.
