The discussion does not show the description. The description defines what the discussion is about and what the issue is. For example it needs to be discussed that something is wrong about the page/article or a statement is disputed. Therefore its very important that the discussion clearly shows the description. I would even go as far as putting the description at the top of each discussion page and putting a clear border around it to make it stand out.
Because the description describes an issue, dispute, etc, 200 characters are not enough for the description. I suggestion to have the full description on the discussion page, while only showing a limited amount of text on the main page.
