So there's a lot to gain in figuring out Reddit's algorithm, which is used to decide what gets on the front page. And Reddit has been harder to trick than other, similar sites, most notably the old version of Digg, which was notoriously easy to fool. (I used to work for Gizmodo, one of Gawker Media's sites, and we had a system to get just about any story on the front page of Digg with a single email. It was shifty.) But now a new blog post has laid out the algorithm, along with some tips and explanation for what gets on the front page and why.
