I don't think I had ever fully internalized how often I open this site throughout the day. Finish a task? HN. Got frustrated/stuck on a problem? HN break. Waiting for something to install/upload/compile/etc? HN. Needless to say I opened a new tab, typed "n", and hit enter countless times today before my brain caught up with my muscle memory.
Yep. Same. It says a lot about the quality of HN, I think. Also, I can't remember the last time it was down. For a while, I thought there must be something wrong with my internet connection or DNS config or something.
That said, HN does have quality content and the signal/noise is way better than sites designed specifically to keep you addicted.
