Why doesn't Treehouse have a Video Comment Section?

I think a sidebar of related useful information is helpful, but comments aren't helpful if they are distracting. I'd rather see fixes or improvements highlighted than a string of comments when the intention is to learn. If important things were shown, I'd agree with your suggestion.

If people use it to add comments, but not point out errors or omissions or improvements since the video was published, then it's useless, in my opinion. Even if that content was allowed, I wouldn't want to see the flow that created it - instead, I'd just want to see the result.

Distraction's dangerous when learning.

That's what Stack Overflow succeeds at due to the compression of the conversation below the main answer, along with the voting system. You only see a few big answers that everyone agrees are pertinent, and you can quickly scan the conversation below it to see how they got there.

Right now Treehouse feels barren to me. I expected some kind of interactivity. I don't think a plain comment section would be useful because it would be a stream of consciousness as bad as Youtube, but this IS a code education site. I think they can come up with something cleverer. :)

The key thing about SO is that the questions are educational in value. In TTH, the lessons are being taught rather than someone asking a question.

IF it can be done correctly, it would be beneficial to point out improvements. Anything other than that's not appropriate and probably a distraction. If it did point out improvements, I'd rather see them rolled into the added material and not part of a conversation.

I'm accustomed to asking questions and talking to my classmates about projects, so I don't see it as being a different setting. And I just don't like the sterile talking box feel that I get from Treehouse. I think most forms of communication and interactivity would be educational on this site since everyone paid to get in here and learn.

I like the idea of an official sidebar for expanded material as well, but I don't think a handful of producers are going to find all the errors and insufficiencies that users will discover over repeated viewings.

I like the idea of a sidebar - but really don't like discussion alongside authoritative material. I'd rather there were linked forum topics you could reference if you wanted to - but not part of the main flow - they are distinct in purpose and I don't think they should be on the same page - this was actually already mentioned in another topic, where some good ideas were listed.

I would rather each chapter had a separate forum dedicated to it (or perhaps a drop down menu in the main forum to easily select the chapter it references, and then can have a link to related chapter posts). Also, it would be interesting if there was a better way to create student groups, so that we can talk to each other and help each other learn outside of just posting in the forums, perhaps like some sort of message/chat option.
