You have a goodwill, but not the whole idea would be good to be implemented.
To be precise, I wouldn't agree with the reward for the top 5 articles, as with ease (years now) you can pay to get votes for your articles, so that won't help that much.
For the PPs, I would say a +5 (so to make it like a hierarchy: CP > Goverment > Congress > Party Presidents, so that would be something like 20, 15, 10 and 5 respectively).
Plus, I don't think this idea will fight the VISA players, but still I would like to see it implemented.
