Since merit system implemented Quality Post word become one of the most used word. But no one describe what is quality post.
There are some members who already described it. But not sure whether it is clear enough or not. Sometimes, I assume the description of
Quality Post is quite subjective, it depends on the individual's perception. So, the answer can be varied and we can't strongly state which one is true or false.
Now come to proper English, this is the requirement of Quality post. Your English should proper like grammar, spell etc. Reality is we can't make high Quality post without know proper English. Although my English is broken but I am trying to learn more. So if you are weak in English then you have to give priority to learn it. Always you have to make unique post, it's very important to make quality post. Copy others post or idea will not consider quality post in my opinions.
Yes, quality post should meet the standard of correct grammatical, constructive, informative, meaningful, and factual. It is surely low quality or even shit post if the post is made by broken grammatical, hard to understand, no point, meaningless, or not according to the fact. About copying other people's ideas, it is a bad way to create a topic. Instead to call as quality post, it is probably categorized as a plagiarism of others' ideas.
