Buzzfeed has a lot of good journalism, apparently. I never go to their site and seek it out, but when it's linked it's very good like this piece.
It shouldn't be so surprising; if CNN and NYT can fill their sites with clickbait, why can't Buzzfeed step in to fill the gap of investigative journalism? Hell, I trust Buzzfeed more than the other two; at least with Buzzfeed you can tell right away whether you're reading clickbait or real journalism.
Buzzfeed mostly is (or was; I pretty much stopped reading it) clickbait but every once in a while they have great in-depth, high-quality articles like this. I suppose it takes much longer to investigate and write these articles than it does to churn out the clickbait.
If you look at the top of this article, you'll see it's actually branded as BuzzFeed News. The BuzzFeed brand itself is still clickbait, BuzzFeed News is the journalism side of things.
I especially like that they have the full data processing code available: https://buzzfeednews.github.io/2017-08-spy-plane-finder/
