This is not really your average front-page at the moment, and in fact it feels significantly more geared towards curiosity and less towards commercial interests compared with the usual. Partly because it's the holiday slow down but you see the same effect on weekends, which is telling. And IMHO hacker news is consistently more curious when America is sleeping.

HN desperately needs tags, which would serve everyone well, whether you're really here for curiosity or for all the corporate news. I'd really like to be able filter out most of the stuff for "working professionals" even if it is still legitimately technical (for example the recent docker and github news). What I usually want is all the hobby tech / PLT / open-source / science / learning-oriented stuff that's left over after that filter. I can imagine various reasons why forcing a "feed" style front-page is advantageous to some people.. but let's just say it's not about promoting curiosity.
