We were inspired by Stan Schroeder . In last January 2007 he published list of Pligg sites based on criteria by which they were chosen were originality of the design and overall quality of the site.
For those not familiar with Pligg, it’s an open source media discovery sites like digg.com.
Best deal site: Dealigg
http://www.dealigg.com
Another social content site based on exchanging deals, Dealigg differentiates itself by using 2 columns for the main content, which works surprisingly well. The voting buttons are non-obtrusive, which makes the whole community part of the site seem more of an afterthought, but that’s ok - on some sites, content is equally important as the community.
Best Internet Marketing site: Sphinn.com
http://www.sphinn.com
This is a social site for search and interactive marketers. It's designed to allow you to share and discover news stories, read and take part in discussions, discover events of interest and network with others.
Best Lifestyle site: Sk-rt.com
