There have been a number of posts about letting Reddit be Reddit and HN be HN, but I think that problems with the level of questions on Reddit is the reason that HN should do them; to provide a more serious place for discussions with these people. It isn't totally uncommon for important people to be on HN already to talk about something they have written, and I think the community has benefited from that.

The point isn't to talk about people, its to talk about ideas with "great minds"
