Johan and I were invited to contribute an article about the Stacks project to Nieuw Archief voor Wiskunde, the journal of the Koninklijk Wiskundig Genootschap (Royal Mathematical Society), describing the project, its history, technical aspects and outlook. The article is not freely available on the webpage yet (all articles eventually become free for the public though), but I am allowed to share it on my webpage.

So if you can read Dutch and want to learn more about the Stacks project, or if your Google Translate skills are on point, click on Het Stacks project.
