Someday there will be something better here, but for now, have some links.
Current project: Codidact, a community-controlled open-source Q&A platform.
New Writing Q&A site for questions about all types of writing -- fiction, technical documentation, scriptwriting, journal articles, poetry, blog posts, and more.
blog.cellio.org, my journal about all sorts of things, but mostly Judaism, science fiction, technology, and random slices of life.
medium.cellio.org, where I mostly write about worldbuilding topics and share some fiction.
