I think it's right if users evaluate good deeds. Users of the platform, by voting, should determine the winners. But for the convenience of users, the platform should be implemented on mobile platforms - IOS, Android, WinMobile. It also requires the ability to directly add and view video from the mobile platform. These steps will make the platform friendlier to the user.
Voting is definitely something we are assessing. The main problem with voting is that you often have these view farms, or click farms which can create fake profiles and vote on a particular profile. That is definitely a way we expect fraud to happen. In our main project this has to be curbed because we cannot have local businesses doing this kind of manipulation. Specially in places that are the most corrupt in the world. We hope to see some of this with deeds and we hope to find solutions for the problems as they arise and take many good lessons from it.
On the mobile discussion, yup, you're bang on.
