Facebook groups
Facebook groups are easy to join and tend to be large and broad, which makes them useful for reach and for finding peers outside the usual developer bubble. Quality varies with moderation, so look for groups with active admins and clear posting rules.
Facebook groups on this page are grouped by what they are about, so you can jump straight to the corner of Facebook you care about.
