I have a good and stable Facebook app running for quite sometime now but I have no time to think of a marketing strategy for this.
Basically this application provides live score update for all major soccer channel. EPL, champions league, and all over the world soccer channel. The meat of this application is that it provides the results using AJAX real-time update without the need to refresh the page. It's fast and efficiently uses caching system for past results.
Suggestion to anyone who is looking to spread their advertising and such can make use of this application to stream and enhance their revenue stream.
