when it comes to technical knowledge on HN, I'm happy when I see a talk f.ex. how huge companies solve tech problems, or conference talks around specific technologies, because it's knowledge very hard or sometimes even impossible to acquire on my own - no matter how hard I would try, I won't have a clue how facebook handles massive deployments or how twitter scales unless somebody from the company publishes it and the community shares it. there is a vast ammount of technical advice/news to share, but toolset tutorials are one google search away, you don't need hn support for that, rtfm.
