4 laws of viral marketing people don't get: 1. The "what" is more important than the "how". A boring product can't be made viral. A remarkable one spreads itself. 2. The best distribution channel is your user. Build sharing directly into the product experience. 3. It's not about getting 1 million views. It's about getting the right 1,000 users who will tell everyone. 4. Emotion spreads faster than features. Make people feel something: delight, surprise, outrage. No one shares "meh."
