I've been reading through the comments here and a lot of this feels familiar to me. When I ask for comments and I don't get any it makes me wonder if people really paid attention to my post. On the other hand, I used to teach and I understand that sometimes people have opinions, suggestions etc but they're too timid to voice them (or it could even be a language barrier issue). One of the things I think we'll need to look into is how people can comment on content they like if they aren't that great with words, they tend to be shy or they're just learning the language.
