I stumbled upon a really interesting group of websites today called Loud3r.com.  According the their website:

LOUD3R is a network of exhaustive, topic-driven websites. We gather and publish the best content from blogs, news and editorial sites, including photos and videos for any given topic. LOUD3R ranks the content, pushing the most important stories to the top. All the news is published by an automated semantic engine that is guided by human editors, user behavior and community feedback.

Loud3r is new, but they have already spoken up enough to get my attention when searching for relevant content!
