Same with me as well.HN is my primary source of news consumption.It also fixed another problem I was facing "Information overload". Before I found HN,I had to skim through all major tech blogs and many newspaper websites.I did use google reader to the fullest in it's haydays :). Now just lurk around here all the time. Also It's not just the links which comes on the front-page but the comments give a completely different perspective from all angles. I would say I love the discussions more than the original content now:)
