I have renewed hope in my startup SocialHelix we have had some new and interesting interest. Plus I know how I want to build the backend now. Graph services are tough.
currently our interface is all in flash, but we have thought about a browser only option that might work on the iPhone or android as a web page.
we have also talked about a potential plugin architecture to make it easy to develop apps on top of our interface. if you know of anyway for us to get a few months worth of funding for it, we would be open to a number of things for out project.
