Hello evanmurphy,

First of all, thank you very much for your reply!

To be honest, I am completely new to Arc and news.arc. I thought building a Hacker-News like forum with news.arc would be faster, but maybe I should be focusing on what I know and build with the languages that I actually know. Is it possible to reverse-engineer? news.arc, because I will probably have a bumpy ride to program "ranking algorithm" like the one used in news.arc (Hacker News).

Hacker News's ranking algorithm isn't public, is it?

At least, it probably isn't in our version of news.arc. As Paul Graham says at http://arclanguage.org/item?id=12468, "I should release a new version though. News.arc is greatly improved since the last release." (I assume the ranking algorithm wouldn't escape scrutiny....)

I've written up a detailed analysis of the published parts of the news.arc ranking algorithm: http://www.arcfn.com/2009/06/how-does-newsyc-ranking-work.ht...

I noticed that a few pieces of the algorithm were not released, and the algorithm has surely changed since arc3.1, but the published code explains at least the overall behavior of Hacker News ranking.
