Agree.
I really don't want "comment" feature on home especially if that means ultimately it's opening the post (only diff thing is it opens a comment which is I'm not sure how many people uses like How many people add the comment after clicking that "Add to comment" button)
I really really hate multiple colors on home screen like "Ask Grapevineers", "Bangalore", IT etc.. it's so disturbing personally.
I know you guys have previously removed the User names from the homepage & now added them. I personally liked the No username interface, because usernames does create biases. Ultimately it's about what you want tho.
Comment UI is very confusing.. and not so intuitive. Alot of times I'm confuse whether I'm replying to someone or adding a root comment.
One suggestion: If somebody deletes their comment, can you show Comment is deleted instead of actually removing it. To atleast show that there was something here, right now it looks pretty stupid.
