The one-liner: When you share info via the Participate option in the app, you are rewarded with free Premium membership. (not sure how that works? See this link)
More info: Even though there are 5 different types of data in Clever Commute, there is a special value to first-person info posted by the commuters. So in order to encourage sharing, we have enhanced the app to automatically credit sharers with days of upgraded service.
The model will evolve...as some categories of information shared may grant you more credits than others. But the point here is that we value your participation...and we want you to directly benefit from your good karma.
