I find the current Flow layout extremely busy and difficult to read. The first time I opened a page with Flow, I was dumbfounded, because it wasn't apparent to me what the topic name, comment text, commenter, etc. were.
What is wrong with the layout that is used in discussions nowadays, with content first and metadata in the background? I think that the comment text should be the most pronounced element, with the author having a slight highlight and all the rest being muted, if I may put it so.
