I'm an elected moderator on Mi Yodeya, The Workplace, and Worldbuilding, and a pro-tempore mod on Writing and Beer, Wine, & Spirits. I've been pretty active on several more sites since I joined the network in 2011 and I think a lot about meta issues, so I think MSE and child metas are pretty important.
Professionally, I'm a technical writer who works with (and often helps design) programming interfaces. I'd love to see more tech-writing questions on Writing.SE.
I write for and help edit Worldbuilding's blog, Universe Factory.
