I have received numerous comments for add-on work already.   This application enriches the data itself while also provided a flexible interface that can be extended.   A couple ideas for sustainability and revenue:  Enriched data - most social actions data is now associated with location data.   this can be fed back into their api for others to use.Nonprofits get their time-critical message across to a specific location - based on user feedback the application feels empowering and makes people want to do something now.   increase user participation for your project or non profit. there is something to be said about seeing others create actions in near real time. when you couple that with the location you can see what people are doing in your area (and team up) or see what people are doing in an area that you care for (say Darfur or Ghana or India).Internal communication for projects - I've already been approached by a few people that said an application like this could facilitate the communication between project partners and collaborator.   This tool could be used internally to create awareness in a near real time way.   Perhaps a projects needs 1 more person in the next 24 hours (a twitter meets social actions meets location) Can be Extended - This can be transformed into a geospatial social actions search engine.   Right now we display all results based on creation date.   But it's fairly straightforward to give a user additional control to filter results based on location or topic of interest.   We could even set up alerts when new results meet their query.
