On many help requests for programs at the project feedback page (https://www.khanacademy.org/computing/computer-programming/projectfeedback), people tend to comment their answers instead of directly answering them, which clogs up the page with already answered questions, and pushed unanswered ones to the bottom. If the question was answered directly, then it would be automatically removed from the list. Sadly, many people don't do that.
Maybe you could add a reminder on the site for people to post answers instead of comments? Or even take the comment feature off of the page, so you can only be at the program itself in order to comment?
