I will not try to address the number of comments, but I've always been pretty lucky that way!
However, regarding the quality of comments I'm noticing a drastic change. I am no longer getting broken English comments from those who obviously aren't reading. I am getting thoughtful and real engagement and that feels great. I wish there was some way to track that! :)
