bitsapphire, I think THAT is the best idea i've heard proposed in months. Has a viral potential built into it. Who has the experience to build such an app? We should green light this kind of project. B
Another idea that has viral potential built into it - application that allows to send some small tips to friends on social networks, something like
https://www.changetip.com/, or another good example is dogetipbot on reddit - I think reddit community did very well using tips to recruit a lot of new users, wouldn't be surprised if this played a major role in dogecoin success. Tipbot doesn't require light client, so it would be easier to implement. A year ago I've started working on something similar for Bitcoin (bitmonetizer.com) but abandoned the project, still have some code that probably can be reused.
