Have you ever walked through a fairground or down a boadwalk. All of a sudden you see a huge crowd of people. Do you check it out? Even if you don't stop, it gets your attention and you have to see what's going on.
Have you ever gone to a restaurant on a Friday night at dinner time and the place is empty? It kind of gets you wondering if there is something wrong. Having a crowd is a great way to get more people interested in what you are doing.
Is there a crowd gathered and clamoring for what you do? What could you do to get a crowd started and the momentum moving forward?
