Biilmann isn&#x27;t at Facebook; he&#x27;s just some random developer at a startup with experience in different languages who once used Haskell for a work project. He may as well be yet another HN commenter, and it isn&#x27;t surprising that not everyone who has tried Haskell is using it! The reporter probably just found him easier to interview than the people actively using Haskell, for whatever reason.<p>Haskell at Facebook is still going strong with, I believe, two teams using it and actively recruiting. (I&#x27;ve been contacted by a recruiter myself, even.) And they&#x27;ve hired Simon Marlowe and Bryan O&#x27;Sullivan who are pretty much as superstar as they come. Recruiting woes are greatly exaggerated if not inverted for startups seeking a handful of engineers—Haskell actively attracts interesting candidates.
