Multiplying or dividing?
If you have a list of 1000 subscribers or 5,000 fans or 10,000 supporters, you have a choice to make.
You can create stories and options and benefits that naturally spread from this group to their friends, and your core group can multiply, with 5,000 growing to 10,000 and then 100,000.
Or you can put the group through a sales funnel, weed out the free riders and monetize the rest. A 5% conversion rate means you just turned 5,000 interested people into 250 paying customers.
Multiplying scales. Dividing helps you make this quarter's numbers.
