I otherwise think bonuses for most merited participants would be an interesting dynamic, rather than those who max out the campaign getting paid the most, in order to encourage quality of posting not just quantity.
Relying on most merited alone can get boring and sometimes unfair.
We do have users here who could just make a few lines or a meme in the Bitcoin wall observer thread, and that would be enough for them to earn 20-30 merits per week, while someone who made constructive posts in other threads could get just 10 merits or even none.
