> Not sure I agree, HN makes the username visible right next to the post?
Yes, but grayed out, in the background, so to speak. I usually do not notice the username at all (capableweb, hi! this is the first time I've noticed you...). Especially the usernames next to topics/stories are completely ignored by my brain's eyes.
Interesting that while your brain seems to ignore the usernames, my brain automatically parses the username when reading the comment, somehow. I'm not thinking about it, it just gets associated automatically.
As I mentioned before, I grew up back when the internet was mostly text, so maybe that's why? Are you perhaps a bit younger than that?
