What is the fine line between quality and quantity and how does it affect merit?
Welcome to the explanation.
If you want to maximize your rank, then you need to increase two statistics which are listed on your profile:
  • Activity, which is maximized by posting once per day on average. Posting more than that is useless in raising your activity.
  • Merit, which is gained by making good posts.

If you make ten thousand posts in a week, your activity will be capped and you will still be a Newbie. If you make ten thousand useless posts over any period of time, you will gain zero merit and you will still be a Newbie. You can rank up only by making good posts consistently. It's quality over quantity.

When trying to write quality posts, a lot of people act as though they're writing a book report for school: putting facts that we already know into their own words. Nobody wants to read that, and you will not get merit for it. Moreover, the length of your post and the quality of your English are only minor factors. In trying to write a quality post worthy of merit, you should offer new ideas, personal experiences, or perspectives that other forum users will actually find new and interesting.

Should people have an alternative way of being rewarded with merits besides posting?
How could this look like, and how would you design the system so it can't be abused?
People already abused it by exchanging their merits, if you see their abuse, report it. No system can prevent they exchanging merits and your question was asked many times but merit system only reduce but don't stop all spammers to rank up.
