You might have probably heard about Pligg. It's a CMS using which you can set up a Digg like site. If you know how to install PHP/MySQL scripts, you can do it yourself. If not or if you don't have time, I can install it for only $5. Sample: http://www.webatyourfeet.com/vote With few modifications, you can have a Pligg site like this. Post here or PM if interested or if you have any questions.
