Does anyone have experience using PHPDug from Kubelabs? I actually do consider starting a product review social bookmarking site. And now I'm looking for the right software to use.
It's ok, kind of difficult to customize compared to some other platforms. If you're looking at launching your own social news/media site like Digg, definitely check out Pligg. The templating system isn't the most straightforward, but if you understand XHTML/CSS and even a little PHP you'll be in really good hands with that CMS.
