My problem - hinted by the term "chat flood" - is that some of the events don't interest me at all. I want to hide redundant submissions! It's times like those when I'm reminded how US-centric HN is. I understand Steve Jobs is an American hero, but many people outside US only want to know that he died. Some major security vulnerabilities fall into this category too. Usually some people with deeper understanding need to take care of it and push the changes upstream. I only need to know to watch out for X or Y hardware or service Z. "Vote on net neutrality" type political submissions - you need to be an US citizen to vote.
