Quantified Prestige needs to be implemented as software, as soon as possible. Why? Because if users and coders can see it and play with it, they will get an intuitive feeling for the idea of a reputation economy. On that basis, it is far easier to attract and recruit more people that can help with the further development.
I've started programming a first demo version of QP, but since I don't have much programming experience, this takes long! It will take months until I can get to a version that implements the most essential basics. What I have created so far after a few weeks of programming is half of a rudimentary registration system, nothing more. I'm not using any framework, but I'm trying to use the model-view-controller pattern properly. What I'm doing at this stage, is more an exercise in programming than anything else.
More serious attempts to create a PHP demo could use parts of the Symfony framework, which is rather popular at the moment.
It would be awesome if there was an experiences PHP programmer who could create a simple QP demo rather quickly. In that case, I would focus on the architecture and the feature set for the demo, rather than the programming implementation.
In any case, it would be cool if programming demo versions of QP would be a joint effort. Just hacking something together that basically works would be much better than nothing. Or at least just thinking about how the QP demo software should be structured (in the MVP pattern sense, with models, views, controllers, files, objects, database tables, functions, whatever) would be cool, too.
