I've been liking Techmeme [1] recently, which presents stories with additional sources and social context from generally knowledgable people. From their about page:
> Techmeme accomplishes this [...] by linking to stories from all around the web. Spotlighting the writings of reporters, commentators, and industry players from across the media and industry landscape [..] sparing readers the impossible task of monitoring an abundance of news sites, tweets, and status updates.
