You're going to get a lot of comments like these because when you say 'natural language' and 'programming' or 'code' in the same sentence people think coding directly in some 'natural'-like language. Also people often don't click on the actual links and many don't necessarily watch endlessly looping video clips when they do. A little bit of verbiage on the site might help that and head off the more obvious-but-inaccurate critiques. .
