I was wondering if there is 'user-driven' and 'clean' news website like HN for semiconductor/telecom/communications/embedded technology segment?

EEtimes/embedded systems design is not user-driven and updates about once a month. Technology categories in topix.com or digg.com are not as clean (crowded by ads) and also there is not enough coverage on low-level details (programming ideas, specific details on standards, new chip architectures etc)
