I think this is an awesome extension with awesome potential, just needs a little more integration with some other community related components. Until then you can reward users manually with pretty pictures next to their avatars and making them show their pros and cons to your community by providing adequate feedback.
Awesome component, modules, plugins, integrates perfectly with JomSocial, amazing support... What more do you need? And it is so cheap compared to its feature richness and robustness. Worth the money in every case.
