Ask HN: Which Wikipedia pages did you start?

There was a thread recently where a person that started a referenced page happened to comment about doing so, and it got me wondering about what types of pages the folks that hang around here start.

Though I contribute to Wikipedia sporadically, the only one I started was before I made an account when I was at The University of Waterloo.

https://en.wikipedia.org/wiki/Resilience

The history doesn't show up because the page was split because it got so large, but I created the page for the structural engineering understanding of the term some time before 2008 after Googling it and not finding anything on my favourite reference site.

What about you?
