I’ve interacted with Bram a few times personally in the process of submitting changes to Vim, and I’ve observed many more interactions with others. I always had an immense amount of respect for the way he led the Vim project and interacted with the community. It is not uncommon to see open source software maintainers become burnt out or frustrated, particularly with a piece of software as quirky and complicated as Vim. But Bram was almost always respectful and patient with users and contributors, even when they were not.
This is a loss for the software world. Bram, you will be missed.
