Regarding the defects of the merit system, I also thought about it. I think there are defects in the following aspects.
1）Merit is concentrated in the English section, and the local section of the merit is more difficult to obtain, and some statistics can prove it. For many non-native English speakers, they also have a lot of high-quality posts in the local section. If the same post is written in English, it may be easier to get Merit and get more Merit. But in the local section, it's hard to get Merit, or only get fewer Merit，this may cause local forums to lack incentives.
This is the fact that the local section lacks the Merit source. It is not like the English section. In local section, there are always some good articles that will be buried.
Therefore, I asked Merit sources, in addition to browsing the English part, can you pay attention to the local part, although language problems may be a big obstacle.
