HN is useful to see what is hot. Hot does not mean it is relevant to all of us. If I am raising money, I would be interested in topics tagged to raising money - the fact that you (fred wilson) posted, up voted, commented the topic is a good signal that topic is relevant.

I also like the idea of commenting system that rapgenius and medium deploys. I believe that the idea of seeing the most up voted comment is broken. You might have something to say on a particular sentence in fund raising article- I'm interested to see that. Others may have interesting things to say about other sentences. If USV can pull content online and allow people to comment each sentence, I believe this would really add value to our community.
