I prefer the headlines here over Reddit’s. What worries me is the quality of the comments. The community and their insightful comments are what keeps me coming back. Lately I've seen an increase in memes and trollish comments from new IDs. I worry that if HN doesn't move to limited account signup period or invite only, it will end up another Slashdot.
