Digg is cool. There is no denying it. It's so cool that you might have thought at one point of running your own Digg-like website. Think about it no more! There are at least three ways for you to run a Digg like site without writing a line of code:

1. First there's Meneame, the source code is commented in Spanish so it may help to speak a little, but you can clearly see that it works by the heavily trafficked production version of the site.

2. Only speak English? There's Pligg which is a branch of Meneame translated and has an active community behind it.

3. DiggClone I haven't tried or seen this one in action and I doubt it's under active development, but if the above two don't work for you, it might be worth checking out.
