Sad to see this. But also not very surprising, given distill has had relatively few or no articles from outside the ediotiral team for years. The combination of extremely polished, interactive articles, and usually great depth made writing for distill a huge challenge. Which makes it not very surprising it was a huge amount of work for the editorial team - I wonder how many articles they helped with that never reached completion. Combined with the lack of incentive for authors to take on the huge amount of work (relative to working on research papers). Still, I hope it indeed inspires more researchers to have personal blogs with in depth articles.
