I am sure almost all internet users know what is Digg. There are a lot of open source digg-clone application for download. I would like to share some of the example of such applications.
- Blinkk – Blinkk is an application which combine digg, del.icio.us, and forum into a platform. View screenshot here.
- Vote up/down Package for Drupal – A plugin for Drupal CMS which can create a voting system which similar with digg.
- PHPDug – An open source digg-clone which support templates and has a very clean interface. It has several extra features such as automatically add stories from RSS feeds and multilingual support. View demo here.
- Vote It Up for Wordpress – It is a Wordpress plugin to create the voting system. It support the latest Wordpress 2.5.
- Upwarded – Simple digg-clone application. But unfortunately i can’t found much information about it.
- Last but not least, Pligg – The most powerful digg-clone application which support templates and plugins. There are a lot of Pligg users, so i believe you can easily get support by the community.
I personally like Pligg and PHPDug over the others as i felt both of them has better interface, which you can modify through the template.
