For the bulk of my professional career, so much editing has gone into everything I’ve produced.

Group editing.
Individual editing.
Self-editing.
When I hit that last form of editing, I need an outlet to say things that can and should be said, but don’t need multiple drafts and final approvals.
For everything else (mostly political, movement, organizing work), this is where I’ve found my latest outlet to say what hasn’t been said by others.
