Yeah, I think it is worth often posting, but that this is only partly because you get feedback and more so for other reasons (e.g., making it more likely that people will find your post/​videos if it’s relevant to them, via seeing it on the home page, finding it in a search, or tags). And comments are generally more useful as feedback than karma, and comments from specific people asked in places outside the Forum are generally more useful as feedback than Forum comments.
