The facts are obvious. Meriting is easier but it's the other way round when you are a source because it becomes a duty you have to use to serve a whole lot of users. The reason I'm able to merit quality most times is because I spend literally more time surfing than posting. A quality post always stands out and in my opinion isn't much difficult to find.
Quality posts are not hard to find, especially the authentic once and not people that will wake up or wait until the time they want before they post on the second page or higher, posting what that has been posted before by many users on the first page. Although, some threads are constructive up to many pages but you can easily know such threads.
Yes, just like you said, there are many good posters and posts in our local board. One thing I think is the major issue here is maybe there is no enough merit allocation available to the moderators or it could be oversight due to many posts from many members. It is not easy to read through all the posts keenly and merit those that is worth it. We all just have to bear with the moderators and focus more on making better posts. Maybe a time will come when your post will be noticed and rewarded.
Make no body panic or come dey vex say they no merit am, our moderators dey try and our Naija Local board no bad at all.
