This is something that I miss about forums of yore and sort of hate about HN, Reddit, and their ilk: the deprioritization of a post author's identity. It took me way too long to figure out you were talking about the username of the person you were replying to. I miss being able to scan through a forum's post listing and readily pick out names of posters I recognized after being involved in the site for a while. It was an additional signal of post quality (or lack thereof, depending on the user). Here, the username is hidden in a sentence of status text, on the same visual level of the number of minutes ago the post was made, all of which is rendered in a light grey font. It's clearly intentional, and I can't for the life of me figure out why the forum owners don't want users to be able to build a consistent identity.
