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.
That's right.
This type of control would only be possible if there were specific rules for attributing merits. Fortunately, that doesn't exist, and it's up to each user to assign merits to the posts they think they should.
What for one user may deserve merit, for another may not. So relying on this to get rewards in campaigns can give a false sense of quality.
The job of a campaign manager, turns out to be a bit like that, to check the quality of posts from registered users. Maybe for the first few weeks, being more attentive to the type of posts that users he doesn't know.
