You're absolutely right, the default subs are the public face of saidit. So any upsetting/contentious subs are intentionally left off of the list. But it does seem like some covid content should be in there.

I'm coding this beast by myself, so I doubt that any serious refactorings of how any of this works will ever be done. We do have a setting to make /s/all your home page though. Anyway thanks for the saidit improvement ideas.
