Buzzfeed has an investigative journalism arm[0] that its built over the last ~7 years. They were a 2018 Pulitzer finalist[1].
I assume their clickbait subsidizes their investigative journalism, a business model that gives me hope given the importance of investigative journalism. Unfortunately that hope is tempered by the recent round of layoffs.
Oddly enough, the major reason I don't trust their investigative reporting was one of the articles that made them a 2018 Pulitzer finalist: https://news.ycombinator.com/item?id=18947852 It was pretty much a conspiracy theory about Russian mind control chemicals disguised as a long-form article about the British police ignoring the supposed assassination of a scientist by the Russians.
