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.
Come with an open mind and have fun if there's interesting stuff that day. Get back to work if there's not. Either way, you win.
The most significant difference I see between 'classic' and 'normal' is the article entitled "First Steps Towards Post scarcity" is 28 on classic, but 13 on normal. Could be there had to be some difference and its random, but I generally find articles on this topic pretty light on quality thinking.
