Maybe since I'm not a newbie on HN anymore I'm remembering through rose-tinted glasses and yelling at the kids to get off my lawn.
The things I care about are programming tips, new software, javascript/python/ruby/etc specific articles, new startup companies. There seems to be a lot less of this kind of content and more general tech news, which I can read at any number of other sites.
I don't care about business stories(other than those related to startups) and rumors Techcrunch has started about something.
On the plus side, the discussions that happen in Comments are definitely still good. I would be great if there was a way to get easier access to the comments than the ity-bity link we have now.
