Some Web3 projects are nailing user acquisition through clever campaign mechanics. Take certain platforms combining quest systems with social proof elements—friends see what others are doing, get curious, jump in. The visibility factor? Massive. When participation becomes visible across networks, FOMO kicks in naturally. No hard sell needed. Just transparent activity feeds showing real engagement, real rewards. That's how you turn casual interest into active communities. The formula isn't rocket science: tie incentives to social actions, make progress visible, watch network effects compound.
