I'm a moderator here and on some other Stack Exchange sites. 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 help edit Mi Yodeya's publications, and I write for and help edit Worldbuilding's blog, Universe Factory. I wrote the SEDE tutorial (with help from jmac and Tim Stone for example queries and formatting, respectively).
