I have been looking into writting a digg like system but I'm having a bit of a problem with the logic of how to make it work.

The part that is getting me is the part about a topic hitting the front page only if it has so many votes in a set amount of time or however they calculate it.

Any tips on where to start or how to go about this? Im not looking for all the fancyness that digg and others have on the site. Just a basic Main page, categories, and upcoming sections.

Also a side note anyone ever used Pligg - Pligg Content Management System or have heard of any other systems that are capabale of doing this?
