+1 for tags. As HN has grown, the topics here have become so broad that it might be months before a particular topic you are interested in like gamedev makes it to the front page. It would be awesome to click a tag and only see submissions about that topic. Or better yet, unclick a tag and filter out submissions about that topic. I'm so sick of AI this and LLM that and DeepFoo and ChatBar, it would be so nice to just delete that noise in my own view of HN's front page.
