James, that is the whole part of really understanding the benefits of your startup. Focused drive makes it easier not only for the viral growth but it also makes it easier to create your overall marketing plan. Just like target market it is the basis for creating a marketing roadmap, Unique Spreading Point is the basis for creating a successful viral plan. This does not mean you stick with that one point forever; in due course, successful companies create many little things to make it easy for their users to spread the word. In the beginning sticking with one main point makes it easier to focus on all fronts including faster entry to the market. The cost and time for getting multiple viral plans in the beginning may be just too high. Hope this helps.
