About me

In December 2005, I co-founded Muppet Wiki, a collaborative encyclopedia about Jim Henson and the Muppets. I instantly fell in love with collaborative writing, and the awesome power of the wiki platform.

Muppet Wiki turned into a huge, beautiful, and deeply peculiar site -- more than 25,000 pages, so far -- and building the wiki quickly became my favorite thing to do. Since 2005, I've made more than 125,000 content edits on Muppet Wiki.

I was the kind of user at Wikia who has tons of ideas about how to make the site better, and I talked a lot to the community and product teams there. By 2007, I'd left my job as an educator at a non-profit agency, moved to San Francisco, and started working for Wikia.

As a Product Manager at Wikia, I worked on lots of different projects, most of them aimed at increasing the number of contributors and contributions on the site. My team built a new Activity Feed, a Create a Wiki workflow, a new Photo Gallery tool, a Theme Designer, a Chat feature, and a Related Pages navigation tool. The most ambitious feature that we built was the Message Wall, a top-to-bottom redesign of MediaWiki's user talk system.

Outside of work, I also write a daily blog called Dark Shadows Every Day, about the 1960s vampire soap opera.

My work

I started working at the Wikimedia Foundation in April 2014. I'm on the Flow team, helping to build the new discussion system.
