I tend to experience this as well. For some reason HN on the weekends has way more interesting and varied topics. The weekday crowd either comes here for more mundane topics, or marketers flood the submission queue, I can't tell which. But I love opening up HN on Saturday mornings and finding some strange retro computing topic. A similar phenomenon also happens if you open up HN before the east coast of north america wakes up on a weekday. The topics tend to be more varied.
