Genuine question : do you think a privacy oriented social network where users pay a small annual fee (around $5) would work? Think Whatsapp (use phone number as an id, no native discovery, only connect through phone contacts, encrypted user data only to prevent database leaks from causing damage) + Facebook (feed like feature, share photos, videos, direct messaging, group messaging). No user tracking, no ads, just a no bullshit social network where the average Joe would feel right at home and also one which the HN crowd would use, assuming social networks have a place in their lives.
