Reddit goes open source

By on

Reddit has made a big announcement today, as of Thursday (or Wednesday in America) the site’s code is open source, under the Common Public Attribution License (CPAL).

The social news site, acquired by Conde Nast in 2006, will allow users work on the site themselves, than petitioning for changes. It now counts 4.5 unique visitors monthly, and though smaller than Digg and Yahoo’s Buzz, it has grown 1,000 percent since Conde Nast bought the site and merged it with its Wired Digitial operations.

However, not all will be released under CPAL. The codes that will remain locked away are related to preventing cheating, ‘gaming’ the system and fighting spam. However, the algorithm that chooses which stories be on the front page will be made to the public.

CPAL is also the same license that Facebook used when it open sourced its platform.
