I agree I've lurked around here for a while but I remember there being a lot less hullabaloo about facebook, google, and apple when I first started browsing and a good amount more about startups, python (and other language) tricks and cool geeky things. I understand that facebook, google, and apple are interesting with how "evil" or "great" they are on a day to day basis but I prefer more geeky articles that wouldn't make it to the front page on reddit.
Though people will just say I'm remembering wrong and saying that quality has dwindled is a figment of my imagination but just look what makes it to the front page on a day to day basis.
It's definitely not your imagination. I see articles here daily that if posted a year ago would have been criticized for not being worthy of Hacker News. Fortunately the discussion here is still mostly civil and intelligent. I've been reading a few haskell papers recently that I'll submit soon, but I think papers are more suitable submissions for weekends so people have time to digest them.
You could always take a look at http://lambda-the-ultimate.org. It's probably isnt exactly what you're looking for, but there are a lot of interesting articles. This is not to say I don't agree with you, but I also remember the erlang/Haskell wave six months ago. Personally, I'm always a big fan of learning new coding techniques and paradigms, like functional snippets but also cool design systems like event-based I/O. I'm sure there's more stuff out there that I don't know of yet.
Am I the only one whose first thought was 'Look, someone else is sick of all the Erlang/Lisp/Scala/Node.js/Haskell articles on HN and has posted a sarcastic request for more of them'?
I'd like that too, but if you're not finding them here, go to twitter. Save some searches tagged with #nodejs, #ruby, #lisp, etc and you'll find loads of links to new articles and developments related to your topic of interest.
