Even I need to think about making a post. At least about 10-20 minutes to make it accompanied by evidence to strengthen the argument. At least there may be participants who are like you said. Quality posts do not have exact standards, this is because the standards of each user's rewards are sometimes different. It's true that sometimes we have periods of decline in quality, but someone who is used to good posts may find it easier to write. But since I joined this time I saw on local forums, bad posts decreased. For global, it doesn't seem to happen much either. It seems that the existence of Merit makes users more eager to create the best reply topic.
