I'm the only person who writes documentation in my department. I continue to do it for my areas, but I'm unsure if it's out of commitment to the mission or spite after failing to get anyone else to write.

I used to write documentation extensively for everything I encountered, and people appreciated it. However, no one else wrote or even added to the documentation.

I got tired of being the only one, so I stopped doing that. Now I just assign issues to people. It got some of them to write really poor documentation, composed of random paragraphs and disjointed bullet lists that don't make sense to anyone but themselves. I stopped getting annoyed by it. If I can't instantly grok it, I just reassign the issue to them and forget about it.
