"what's the viral hook in your product?"
The science of Velcro is simple. One side of the material is composed of
thousands of tiny "hooks," while the other side is made of just as many "loops."
When the hooks engage with the loops, they stick.
And that's why Web 2.0 is Velcro. Marketers, designers and developers alike are
scrambling to figure how two things:
1. What are the viral "hooks" that
capture people's attention?
2. What are the viral "loops," which create
infinite engagement that spreads like wildfire?
