Hacker News Reader

I don't think he meant anything by the comment, other than simplifying access to more (older) comments. ;)

Correct. I've read the original post years ago, I do find it it fascinating, and I would like every new generation to read it. I don't have a quarrel with it making HN front page every now and then.

Probably this is why he put here those links, to redirect the new set of users to discussions from the old set of users.

It's useful for the new users too because previous discussions has a lot of comments to read.

By the way, it would be great if there would be a "Related" widget with the number of comments somewhere in the comment page.

Clicking on the domain name is close to that.

As they say, close but no cigar. I come to the comments and find previous discussion because of a helpful user. Not because I knew to look for it.
