That's.. a good point.
Yesterday, I was listening to a podcast about publishing and they had a guy from Delayed Gratification on - http://www.dgquarterly.com/ .. it's a quarterly "slow journalism" magazine that summarizes the news of the last 3 months and follows up with that news (extra things that happened, reactions, etc.)
Maybe something similar would work for Hacker News. We have Hacker Monthly which beautifully brings together a handful of interesting articles, but it's not really analysis or summarizing the last three months in terms of trends, goings-ons and the aftermath of what occurred.
Should this exist? If not for Hacker News, then the tech scene in general? I'd subscribe to such a publication even if only for archival & reference purposes.
