What are the criteria to conclude that the post is with quality?
The length? The statement? The point? The credibility of the writer? Or is it just upon the discretion of the reader?
Different members have different criteria to judge a quality post. Here is what I consider as a quality post:
1) First thing is that it should contain unique information. If the response i just rephrasing the content posted in other replies, it is useless even if it is of considerable length. Also, it should answer the query in simple language. For instance, suppose a new member has asked about legal issues related to bitcoins. This should be explained giving specific examples like laws in a particular country.
2) Next thing we should consider is how responsive or active is the member. If he has responded to the query earlier, he should be given preference.
