Core idea
Loose, “weak” social connections are disproportionately powerful for spreading information and creating opportunities.
Why I care
Explains why tiny social features (follows, lightweight sharing, referrals) can outperform giant in‑product billboards when you’re trying to grow.
Great for
Referral flows, virality loops, B2B invite mechanics, and anything community‑ish.
Key concept to Google
Bridging vs bonding social capital
Difficulty
Medium—classic sociology style, but the main punchline is super portable.
