changemyview’s description centres willingness to revise. unpopularopinion’s description centres sharing unpopular opinions. That intent gap is the useful distinction—not subscriber counts.

Where this comparison comes from

Public titles/descriptions and member counts from SubMouse’s SFW directory (see page date). Direct directory related-link changemyview → unpopularopinion. Activity sample for unpopularopinion from our collector. Rule lines were not available for both sides in the same snapshot, so we do not invent them.

Members and public descriptions come from SubMouse's safe-for-work directory (as of 2026-11-02 UTC); 7-day growth measured from 2026-10-26. Posts/day and post-type mixes appear when we have an activity sample. Rule lines are short titles, not the full sidebar. Directory rank is listing order — communities outside the current Top 100 open in the info tool instead of a full community page.
