Buzzfeed, AFAIK, was blacklisted from HN for awhile, but it looks like the new mod regime has taken off the blanket ban...and that's a good thing. The majority of Buzzfeed is still linkbait but they do have sections written by real reporters, with some of the best writing and research I've seen from online outlets. My personal favorite was this in-depth exoneration of MSG: http://www.buzzfeed.com/johnmahoney/the-notorious-msgs-unlik...

disclosure: one of my former colleagues is a Buzzfeed editor (http://www.usatoday.com/story/money/columnist/rieder/2014/02...), and he's been in charge of hiring an investigations team. He's a Pulitzer winner himself and just hired one of this year's Pulitzer winners, as well as a Pulitzer finalist (HN user jsvine)...the late Michael Hastings was doing investigative reporting for Buzzfeed before his untimely death. So the investment they're putting into non-listicle-journalism is non-trivial.
