I see two links in his HN bio.

Seems not everyone is aware so I'll just point it out:

The bio can be found by clicking peoples username.

From the bio you can also navigate to their comment history and also see what stories they have submitted.

If someone isn’t aware of this they are not my preferred peer.

To add to my answer from yesterday: there is also no obvious way to see that usernames are links (at least for me, somewhat colorblind on a mobile device.)

If it's any comfort to you, it's the same for normal-sighted (everything's gray).

They probably think that users like to have to hunt for the features of the site.
