The problem is that what we have built is very, very broad, so narrowing it is difficult.
The platform lets you send people little bundles of UI and have them interact. That's incredibly broad and vague!
So here are some examples: You could get them to take pictures of all the storefronts in a town. You could send them realtime surveys to go along with a television show. You could have them rate sessions at a conference. You could have someone be notified when they walk onto a car dealership and offer them the chance to look up car prices.
Explaining this with one line has been very difficult so far. My favorites so far are: 1) Turn a passive audience into engaged particpants. 2) Turn your audience int your army.
