From what I've seen, meta is the only forum where people are willing to give out merit. No one in the altcoin forums is willing to use it. I've made numerous posts that have gotten "thank you" replies, but no one has clicked the button yet. Then I come in here and I see people giving it out left and right just for sharing an opinion or being well known.
If you have observed this, then simple post quality posts in meta. All sections need quality content here. Also, there are a lot of users asking questions about the merit system. So, you should learn the latest developments related to merit system and update other members.
